Title
LibreChat: 2FA Backup Code Regeneration Without OTP Verification Allows 2FA Bypass
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the POST /api/auth/2fa/backup/regenerate endpoint regenerates all 2FA backup codes without requiring any TOTP token or existing backup code verification. An attacker with a stolen session token can silently replace a victim's backup codes and use them to bypass 2FA login or disable 2FA entirely. This vulnerability is fixed in 0.8.4-rc1.

Title
LibreChat: Incomplete Fix for CVE-2025-7105 — /api/convos/duplicate Lacks Rate Limiting Applied to /api/convos/fork
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the fix for CVE-2025-7105 added forkIpLimiter and forkUserLimiter rate limiters to POST /api/convos/fork to prevent rapid-fire conversation duplication. However, the POST /api/convos/duplicate endpoint — which is in the same file and performs the exact same expensive database operations — was not given any rate limiter. An authenticated user can bypass the CVE-2025-7105 fix by using /duplicate instead of /fork to exhaust server resources. This vulnerability is fixed in 0.8.4-rc1.

Title
LibreChat: SSRF via User-Provided Custom Endpoint baseURL — no private IP validation on user-configured API base URLs
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, LibreChat allows users to configure custom OpenAI-compatible API endpoints by setting a baseURL. This URL is used to construct HTTP requests without any SSRF validation — no private IP check, no scheme restriction, no DNS pinning. An authenticated user can set baseURL to internal network addresses. This vulnerability is fixed in 0.8.4-rc1.

LibreChat: Missing Resource Parameter Validation in MCP OAuth Flow
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.5, LibreChat's MCP OAuth implementation does not validate that the resource parameter from OAuth Protected Resource metadata (RFC 9728) matches the configured MCP server URL, allowing a malicious MCP server to steal access tokens intended for a legitimate server. This vulnerability is fixed in 0.8.5.

LibreChat: IDOR in Message Deletion — Incomplete Fix for CVE-2024-41703 Leaves deleteMessages() Without User Filter
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the DELETE /api/messages/:conversationId/:messageId endpoint allows any authenticated user to delete any other user's messages. The validateMessageReq middleware only validates that the conversationId belongs to the requesting user, but the handler calls deleteMessages({ messageId }) using only the messageId as the MongoDB filter — without adding a user constraint. An attacker provides their own valid conversationId (to pass validation) and the victim's messageId (to target deletion), resulting in permanent, irrecoverable message deletion. This vulnerability is fixed in 0.8.4-rc1.

Title
LibreChat: Image Upload Route Bypasses Agent Permission Check — Incomplete Fix for File Upload Authorization
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the POST /api/files/images endpoint allows any authenticated user to upload files into any agent's tool_resources (e.g., context, execute_code) without verifying ownership or EDIT permission on the target agent. A permission check was added to the POST /api/files route in a previous patch, but the image upload route was never updated with the same check. An attacker can simply use the image endpoint instead of the file endpoint to bypass the authorization entirely. This vulnerability is fixed in 0.8.4-rc1.

Title
LibreChat: Stored XSS via unescaped image alt text in markdown artifact preview
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, there is a vulnerability in LibreChat's markdown artifact preview pipeline. The marked library v15.0.12 does not HTML-escape double-quote characters in image alt text when a custom renderer falls through to the default renderer. LibreChat's generateMarkdownHtml function (in client/src/utils/markdown.ts) installs a custom image renderer that returns false for URLs passing the isSafeUrl allowlist check, which causes marked to fall back to its built-in renderer. That built-in renderer inserts the raw alt text into the alt="..." attribute without escaping double-quote characters. An attacker can craft an alt text such as " onload="payload to break out of the attribute and inject an arbitrary event handler. The resulting HTML is then assigned to document.getElementById('content').innerHTML inside the Sandpack preview iframe, causing the payload to execute in the victim's browser. This vulnerability is fixed in 0.8.4-rc1.

LibreChat: Incomplete Fix for CVE-2024-11171 — Conversation Import Multer Instance Missing File Size Limits
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the fix for CVE-2024-11171 (commit bb58a2d0) added limits: { fileSize } to createMulterInstance() in the file upload routes. However, the POST /api/convos/import endpoint uses a separate multer instance that was never updated with the same limits configuration. Combined with the application-level size check being disabled by default (the CONVERSATION_IMPORT_MAX_FILE_SIZE_BYTES env var is commented out in .env.example), an authenticated user can upload arbitrarily large files to exhaust server disk space and memory. This vulnerability is fixed in 0.8.4-rc1.

Title
LibreChat: 2FA Re-enrollment Allows Full Account 2FA Takeover Without OTP Verification
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the GET /api/auth/2fa/enable endpoint can be called by an authenticated user (or attacker with a stolen session) even when 2FA is already fully enabled on the account. This endpoint overwrites the existing TOTP secret, generates new backup codes, and sets twoFactorEnabled to false — all without requiring any TOTP or backup code verification. An attacker with a valid session token can completely take over a victim's 2FA, locking the legitimate user out of their own two-factor authentication. This vulnerability is fixed in 0.8.4-rc1.

Title
LibreChat: Shared-agent editor can globally delete owner's file records — breaks owner's other private agents
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. In versions up to and including 0.8.3, a shared-agent editor can delete file records through `DELETE /api/files` that the owner has reused across multiple agents. The deletion removes the file globally — not just from the shared agent — breaking the owner's other private agents that reference the same `file_id`. The private agent retains a stale `file_id` reference that no longer resolves. A shared-agent editor can destroy files that the owner uses across multiple agents. The owner's private agents — which the attacker has no access to — break silently with stale `file_id` references. This is a cross-agent integrity violation: editing access to one agent should not affect another. Version 0.8.4 contains a patch.

Title
LibreChat Shared MCP Server View Leaks Decrypted Admin Secrets
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. In versions up to and including 0.8.3, users with only `VIEW` access to an MCP server can retrieve the server's decrypted admin-managed secrets through `GET /api/mcp/servers` and `GET /api/mcp/servers/:serverName`. The returned config includes plaintext values for `apiKey.key` and `oauth.client_secret`. This allows viewers of a shared MCP server to exfiltrate the underlying provider credentials. Version 0.8..4 contains a patch. Other remediations include: never returning decrypted admin-managed secrets to non-owners; redacting apiKey.key and oauth.client_secret from all API responses consider returning only boolean presence indicators for secrets, similar to the auth-values route pattern; and, if owners need to edit configs without re-entering secrets, preserving secrets server-side and returning placeholders instead of plaintext.

Title
LibreChat Exfiltrates Server Secrets via MCP Server URL Injection
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. In versions up to and including 0.8.3, the Model Context Protocol (MCP) server integration resolves ${VAR} placeholders against the server's process.env during Zod schema validation of user-supplied MCP server URLs. Any authenticated user can create a malicious MCP server configuration with a URL pointing to an attacker-controlled domain containing environment variable references, causing the LibreChat server to connect to the attacker's server and transmit critical secrets such as CREDS_KEY, CREDS_IV, JWT_SECRET, and MONGO_URI in the request URL. This enables full compromise of the installation's cryptographic materials and database credentials without requiring administrative privileges. This is patched in version 0.8.4-rc1.

Title
LibreChat has IDOR in API Keys Management that allows any authenticated user to overwrite other users' API keys
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. In versions up to and including 0.7.6, an Insecure Direct Object Reference (IDOR) vulnerability exists in the API keys management endpoint (PUT /api/keys). Due to the use of the JavaScript object spread operator after setting the authenticated user's ID, any authenticated user can inject a userId parameter in the request body to overwrite any other user's API keys (e.g., OpenAI, Anthropic, Azure). This allows an attacker to replace a victim's API key configuration, potentially routing the victim's conversations through attacker-controlled keys or denying service by providing invalid keys. This is patched in version 0.8.3-rc1.

Title
LibreChat Affected by Arbitrary File Write via `execute_code` Artifact Filename Traversal
Summary
LibreChat is a ChatGPT clone with additional features. Prior to 0.8.4, LibreChat trusts the name field returned by the execute_code sandbox when persisting code-generated artifacts. On deployments using the default local file strategy, a malicious artifact filename containing traversal sequences (for example, ../../../../../app/client/dist/poc.txt) is concatenated into the server-side destination path and written with fs.writeFileSync() without sanitization. This gives any user who can trigger execute_code an arbitrary file write primitive as the LibreChat server user. This vulnerability is fixed in 0.8.4.

Title
LibreChat's MCP Server Header Injection Enables OAuth Token Theft
Summary
LibreChat is a ChatGPT clone with additional features. In versions 0.8.2-rc1 through 0.8.3-rc1, user-created MCP (Model Context Protocol) servers can include arbitrary HTTP headers that undergo credential placeholder substitution. An attacker can create a malicious MCP server with headers containing `{{LIBRECHAT_OPENID_ACCESS_TOKEN}}` (and others), causing victims who call tools on that server to have their OAuth tokens exfiltrated. Version 0.8.3-rc2 fixes the issue.

LibreChat's IDOR in SSE Stream Subscription Allows Reading Other Users' Chats
Summary
LibreChat is a ChatGPT clone with additional features. In versions 0.8.2-rc2 through 0.8.2-rc3, the SSE streaming endpoint `/api/agents/chat/stream/:streamId` does not verify that the requesting user owns the stream. Any authenticated user who obtains or guesses a valid stream ID can subscribe and read another user's real-time chat content, including messages, AI responses, and tool invocations. Version 0.8.2 patches the issue.

LibreChat: Incomplete Fix for CVE-2024-11171 — Conversation Import Multer Instance Missing File Size Limits
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the fix for CVE-2024-11171 (commit bb58a2d0) added limits: { fileSize } to createMulterInstance() in the file upload routes. However, the POST /api/convos/import endpoint uses a separate multer instance that was never updated with the same limits configuration. Combined with the application-level size check being disabled by default (the CONVERSATION_IMPORT_MAX_FILE_SIZE_BYTES env var is commented out in .env.example), an authenticated user can upload arbitrarily large files to exhaust server disk space and memory. This vulnerability is fixed in 0.8.4-rc1.

LibreChat: Stored XSS via unescaped image alt text in markdown artifact preview
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, there is a vulnerability in LibreChat's markdown artifact preview pipeline. The marked library v15.0.12 does not HTML-escape double-quote characters in image alt text when a custom renderer falls through to the default renderer. LibreChat's generateMarkdownHtml function (in client/src/utils/markdown.ts) installs a custom image renderer that returns false for URLs passing the isSafeUrl allowlist check, which causes marked to fall back to its built-in renderer. That built-in renderer inserts the raw alt text into the alt="..." attribute without escaping double-quote characters. An attacker can craft an alt text such as " onload="payload to break out of the attribute and inject an arbitrary event handler. The resulting HTML is then assigned to document.getElementById('content').innerHTML inside the Sandpack preview iframe, causing the payload to execute in the victim's browser. This vulnerability is fixed in 0.8.4-rc1.

Title
LibreChat: Image Upload Route Bypasses Agent Permission Check — Incomplete Fix for File Upload Authorization
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the POST /api/files/images endpoint allows any authenticated user to upload files into any agent's tool_resources (e.g., context, execute_code) without verifying ownership or EDIT permission on the target agent. A permission check was added to the POST /api/files route in a previous patch, but the image upload route was never updated with the same check. An attacker can simply use the image endpoint instead of the file endpoint to bypass the authorization entirely. This vulnerability is fixed in 0.8.4-rc1.

LibreChat: IDOR in Message Deletion — Incomplete Fix for CVE-2024-41703 Leaves deleteMessages() Without User Filter
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the DELETE /api/messages/:conversationId/:messageId endpoint allows any authenticated user to delete any other user's messages. The validateMessageReq middleware only validates that the conversationId belongs to the requesting user, but the handler calls deleteMessages({ messageId }) using only the messageId as the MongoDB filter — without adding a user constraint. An attacker provides their own valid conversationId (to pass validation) and the victim's messageId (to target deletion), resulting in permanent, irrecoverable message deletion. This vulnerability is fixed in 0.8.4-rc1.

LibreChat: SSRF via User-Provided Custom Endpoint baseURL — no private IP validation on user-configured API base URLs
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, LibreChat allows users to configure custom OpenAI-compatible API endpoints by setting a baseURL. This URL is used to construct HTTP requests without any SSRF validation — no private IP check, no scheme restriction, no DNS pinning. An authenticated user can set baseURL to internal network addresses. This vulnerability is fixed in 0.8.4-rc1.

LibreChat: Incomplete Fix for CVE-2025-7105 — /api/convos/duplicate Lacks Rate Limiting Applied to /api/convos/fork
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the fix for CVE-2025-7105 added forkIpLimiter and forkUserLimiter rate limiters to POST /api/convos/fork to prevent rapid-fire conversation duplication. However, the POST /api/convos/duplicate endpoint — which is in the same file and performs the exact same expensive database operations — was not given any rate limiter. An authenticated user can bypass the CVE-2025-7105 fix by using /duplicate instead of /fork to exhaust server resources. This vulnerability is fixed in 0.8.4-rc1.

Title
LibreChat: 2FA Backup Code Regeneration Without OTP Verification Allows 2FA Bypass
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the POST /api/auth/2fa/backup/regenerate endpoint regenerates all 2FA backup codes without requiring any TOTP token or existing backup code verification. An attacker with a stolen session token can silently replace a victim's backup codes and use them to bypass 2FA login or disable 2FA entirely. This vulnerability is fixed in 0.8.4-rc1.

Title
LibreChat: 2FA Re-enrollment Allows Full Account 2FA Takeover Without OTP Verification
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the GET /api/auth/2fa/enable endpoint can be called by an authenticated user (or attacker with a stolen session) even when 2FA is already fully enabled on the account. This endpoint overwrites the existing TOTP secret, generates new backup codes, and sets twoFactorEnabled to false — all without requiring any TOTP or backup code verification. An attacker with a valid session token can completely take over a victim's 2FA, locking the legitimate user out of their own two-factor authentication. This vulnerability is fixed in 0.8.4-rc1.

Title
LibreChat: Shared-agent editor can globally delete owner's file records — breaks owner's other private agents
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. In versions up to and including 0.8.3, a shared-agent editor can delete file records through `DELETE /api/files` that the owner has reused across multiple agents. The deletion removes the file globally — not just from the shared agent — breaking the owner's other private agents that reference the same `file_id`. The private agent retains a stale `file_id` reference that no longer resolves. A shared-agent editor can destroy files that the owner uses across multiple agents. The owner's private agents — which the attacker has no access to — break silently with stale `file_id` references. This is a cross-agent integrity violation: editing access to one agent should not affect another. Version 0.8.4 contains a patch.

Title
LibreChat Shared MCP Server View Leaks Decrypted Admin Secrets
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. In versions up to and including 0.8.3, users with only `VIEW` access to an MCP server can retrieve the server's decrypted admin-managed secrets through `GET /api/mcp/servers` and `GET /api/mcp/servers/:serverName`. The returned config includes plaintext values for `apiKey.key` and `oauth.client_secret`. This allows viewers of a shared MCP server to exfiltrate the underlying provider credentials. Version 0.8..4 contains a patch. Other remediations include: never returning decrypted admin-managed secrets to non-owners; redacting apiKey.key and oauth.client_secret from all API responses consider returning only boolean presence indicators for secrets, similar to the auth-values route pattern; and, if owners need to edit configs without re-entering secrets, preserving secrets server-side and returning placeholders instead of plaintext.

Title
LibreChat Exfiltrates Server Secrets via MCP Server URL Injection
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. In versions up to and including 0.8.3, the Model Context Protocol (MCP) server integration resolves ${VAR} placeholders against the server's process.env during Zod schema validation of user-supplied MCP server URLs. Any authenticated user can create a malicious MCP server configuration with a URL pointing to an attacker-controlled domain containing environment variable references, causing the LibreChat server to connect to the attacker's server and transmit critical secrets such as CREDS_KEY, CREDS_IV, JWT_SECRET, and MONGO_URI in the request URL. This enables full compromise of the installation's cryptographic materials and database credentials without requiring administrative privileges. This is patched in version 0.8.4-rc1.

Title
LibreChat has IDOR in API Keys Management that allows any authenticated user to overwrite other users' API keys
Summary
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. In versions up to and including 0.7.6, an Insecure Direct Object Reference (IDOR) vulnerability exists in the API keys management endpoint (PUT /api/keys). Due to the use of the JavaScript object spread operator after setting the authenticated user's ID, any authenticated user can inject a userId parameter in the request body to overwrite any other user's API keys (e.g., OpenAI, Anthropic, Azure). This allows an attacker to replace a victim's API key configuration, potentially routing the victim's conversations through attacker-controlled keys or denying service by providing invalid keys. This is patched in version 0.8.3-rc1.

Title
LibreChat Affected by Arbitrary File Write via `execute_code` Artifact Filename Traversal
Summary
LibreChat is a ChatGPT clone with additional features. Prior to 0.8.4, LibreChat trusts the name field returned by the execute_code sandbox when persisting code-generated artifacts. On deployments using the default local file strategy, a malicious artifact filename containing traversal sequences (for example, ../../../../../app/client/dist/poc.txt) is concatenated into the server-side destination path and written with fs.writeFileSync() without sanitization. This gives any user who can trigger execute_code an arbitrary file write primitive as the LibreChat server user. This vulnerability is fixed in 0.8.4.
