Title
LobeChat 2.2.1 Webhook Signature Verification Bypass QQ Feishu
Summary
LobeChat (LobeHub) 2.2.1 does not properly verify inbound chat-platform webhook signatures in the QQ and Feishu adapters. The webhook route (/api/agent/webhooks/:platform) is unauthenticated by design and delegates verification to each adapter; the QQ adapter performs no Ed25519 signature verification on dispatched message events, and the Feishu adapter only performs an optional static-token comparison that is skipped when no token is configured (the default) and is not a body signature. An unauthenticated attacker who knows the public webhook URL can POST forged inbound messages with an attacker-chosen sender identity and arbitrary text, causing the bot owner's agent to process attacker-controlled input and treat the attacker as a trusted platform sender.

Title
LobeChat 2.2.9 - Broken Object Level Authorization via Chat-Group Agent Operations
Summary
LobeChat through 2.2.9 contains a broken object level authorization vulnerability that allows authenticated attackers to access and modify other users' chat-group agent data by supplying arbitrary group identifiers. Attackers can invoke the getGroupAgents, updateAgentInGroup, and removeAgentsFromGroup operations without user-scoped predicates to read agent listings, modify agent roles and ordering, and remove agents from chat groups belonging to other users.

Title
LobeChat < 2.2.10-canary.18 - SSRF via importFromUrl and fetchImageFromUrl
Summary
LobeChat before 2.2.10-canary.18 contains a server-side request forgery vulnerability that allows authenticated attackers to direct internal HTTP requests to arbitrary URLs by supplying user-controlled input to the skill import service (importFromUrl) and topic cover update (fetchImageFromUrl) endpoints, which use the global fetch without the project's ssrf-safe-fetch wrapper. Attackers can target internal addresses such as cloud instance metadata endpoints through these unprotected code paths to disclose internal service responses and cloud credentials.

Title
LobeChat 2.2.9 - Broken Object-Level Authorization in Message Sub-Resource Writes
Summary
LobeChat through 2.2.9 server-database deployments are vulnerable to broken object-level authorization in MessageModel. The updateMessagePlugin, updatePluginState, updatePluginError, updateTTS and updateTranslate methods filter target rows by message id alone, omitting the userId scope that sibling methods apply, and findMessagePlugin reads back by id alone. Reachable via the corresponding tRPC message procedures, an authenticated user who knows another user's message identifier can overwrite that victim's plugin tool-call metadata, plugin state/error, text-to-speech and translation records on the same instance, and the tampered content is served back to the victim. Exploitation requires knowledge of the victim's non-enumerable message identifier.

Title
LobeChat < 2.2.10-canary.15 - Regular Expression Denial of Service in GitHub Skill Import
Summary
LobeChat before version 2.2.10-canary.15 contains a regular expression denial of service (ReDoS) vulnerability that allows authenticated attackers to block the Node.js event loop by supplying a catastrophic-backtracking pattern in a GitHub repository URL path during skill import. Attackers can craft a malicious basePath value containing unescaped regex metacharacters such as catastrophic-backtracking patterns, which are injected into a dynamically constructed regular expression in the findSkillMd function and executed synchronously against archive entries, denying service to all concurrent users for tens of seconds per request.

LobeHub: Unauthenticated SSRF in `/webapi/proxy`
Summary
LobeHub is a work-and-lifestyle space to find, build, and collaborate with agent teammates that grow with you. Prior to 2.1.57, the /webapi/proxy endpoint on app.lobehub.com accepts a URL in the POST body and fetches it server-side without any authentication. An attacker can use this to make arbitrary outbound requests from LobeHub's infrastructure, leak Vercel deployment details, and inject cookies on the lobehub.com domain through reflected Set-Cookie headers. This vulnerability is fixed in 2.1.57.

Title
LobeHub: Cross-Site Scripting(XSS) escalate to Remote Code Execution(RCE)
Summary
LobeHub is a work-and-lifestyle space to find, build, and collaborate with agent teammates that grow with you. Prior to 2.1.48, when LobeChat processes custom tags in the Render process of src/features/Portal/Artifacts/Body/Renderer/index.tsx, if no type match is found, it will choose to call the default method, HTMLRenderer, for HTML rendering. If an attacker can induce the LLM to output content containing malicious tags, an XSS vulnerability can be created on the client side. Additionally, Lobechat's Electron main process exposes an IPC interface called runCommand, used to invoke system commands. This interface allows arbitrary command execution and does not filter the command parameter. Therefore, if an attacker can obtain a handle to window.parent.electronAPI via XSS and call the runCommand method of the IPC, the ipcMain process can execute arbitrary system commands with the current user's privileges. This vulnerability is fixed in 2.1.48.

Title
LobeHub has an unauthenticated authentication bypass on `webapi` routes via forgeable `X-lobe-chat-auth` header
Summary
LobeHub is a work-and-lifestyle space to find, build, and collaborate with agent teammates that grow with you. Prior to 2.1.48, the webapi authentication layer trusts a client-controlled X-lobe-chat-auth header that is only XOR-obfuscated, not signed or otherwise authenticated. Because the XOR key is hardcoded in the repository, an attacker can forge arbitrary auth payloads and bypass authentication on protected webapi routes. Affected routes include /webapi/chat/[provider], /webapi/models/[provider], /webapi/models/[provider]/pull, and /webapi/create-image/comfyui. This vulnerability is fixed in 2.1.48.

Title
LobeChat 2.2.1 Webhook Signature Verification Bypass QQ Feishu
Summary
LobeChat (LobeHub) 2.2.1 does not properly verify inbound chat-platform webhook signatures in the QQ and Feishu adapters. The webhook route (/api/agent/webhooks/:platform) is unauthenticated by design and delegates verification to each adapter; the QQ adapter performs no Ed25519 signature verification on dispatched message events, and the Feishu adapter only performs an optional static-token comparison that is skipped when no token is configured (the default) and is not a body signature. An unauthenticated attacker who knows the public webhook URL can POST forged inbound messages with an attacker-chosen sender identity and arbitrary text, causing the bot owner's agent to process attacker-controlled input and treat the attacker as a trusted platform sender.

Title
LobeChat 2.2.9 - Broken Object Level Authorization via Chat-Group Agent Operations
Summary
LobeChat through 2.2.9 contains a broken object level authorization vulnerability that allows authenticated attackers to access and modify other users' chat-group agent data by supplying arbitrary group identifiers. Attackers can invoke the getGroupAgents, updateAgentInGroup, and removeAgentsFromGroup operations without user-scoped predicates to read agent listings, modify agent roles and ordering, and remove agents from chat groups belonging to other users.

LobeChat 2.2.9 - Cross-User Document Disclosure via Unscoped RAG Semantic Search
Summary
LobeChat through 2.2.9 contains a broken access control vulnerability in the retrieval-augmented-generation semantic search functionality that allows authenticated attackers to access other users' data by exploiting missing user-identifier predicates in the chunk model semanticSearch method. Attackers can supply arbitrary victim file or knowledge-base identifiers through the chunk retrieval and chat knowledge-base paths to retrieve text content, file names, and metadata belonging to other users.

LobeChat < 2.2.10-canary.18 - SSRF via importFromUrl and fetchImageFromUrl
Summary
LobeChat before 2.2.10-canary.18 contains a server-side request forgery vulnerability that allows authenticated attackers to direct internal HTTP requests to arbitrary URLs by supplying user-controlled input to the skill import service (importFromUrl) and topic cover update (fetchImageFromUrl) endpoints, which use the global fetch without the project's ssrf-safe-fetch wrapper. Attackers can target internal addresses such as cloud instance metadata endpoints through these unprotected code paths to disclose internal service responses and cloud credentials.

Title
LobeChat 2.2.9 - Broken Object-Level Authorization in Message Sub-Resource Writes
Summary
LobeChat through 2.2.9 server-database deployments are vulnerable to broken object-level authorization in MessageModel. The updateMessagePlugin, updatePluginState, updatePluginError, updateTTS and updateTranslate methods filter target rows by message id alone, omitting the userId scope that sibling methods apply, and findMessagePlugin reads back by id alone. Reachable via the corresponding tRPC message procedures, an authenticated user who knows another user's message identifier can overwrite that victim's plugin tool-call metadata, plugin state/error, text-to-speech and translation records on the same instance, and the tampered content is served back to the victim. Exploitation requires knowledge of the victim's non-enumerable message identifier.

Title
LobeChat < 2.2.10-canary.15 - Regular Expression Denial of Service in GitHub Skill Import
Summary
LobeChat before version 2.2.10-canary.15 contains a regular expression denial of service (ReDoS) vulnerability that allows authenticated attackers to block the Node.js event loop by supplying a catastrophic-backtracking pattern in a GitHub repository URL path during skill import. Attackers can craft a malicious basePath value containing unescaped regex metacharacters such as catastrophic-backtracking patterns, which are injected into a dynamically constructed regular expression in the findSkillMd function and executed synchronously against archive entries, denying service to all concurrent users for tens of seconds per request.

Title
LobeHub: Unauthenticated SSRF in `/webapi/proxy`
Summary
LobeHub is a work-and-lifestyle space to find, build, and collaborate with agent teammates that grow with you. Prior to 2.1.57, the /webapi/proxy endpoint on app.lobehub.com accepts a URL in the POST body and fetches it server-side without any authentication. An attacker can use this to make arbitrary outbound requests from LobeHub's infrastructure, leak Vercel deployment details, and inject cookies on the lobehub.com domain through reflected Set-Cookie headers. This vulnerability is fixed in 2.1.57.

Title
LobeHub: Cross-Site Scripting(XSS) escalate to Remote Code Execution(RCE)
Summary
LobeHub is a work-and-lifestyle space to find, build, and collaborate with agent teammates that grow with you. Prior to 2.1.48, when LobeChat processes custom tags in the Render process of src/features/Portal/Artifacts/Body/Renderer/index.tsx, if no type match is found, it will choose to call the default method, HTMLRenderer, for HTML rendering. If an attacker can induce the LLM to output content containing malicious tags, an XSS vulnerability can be created on the client side. Additionally, Lobechat's Electron main process exposes an IPC interface called runCommand, used to invoke system commands. This interface allows arbitrary command execution and does not filter the command parameter. Therefore, if an attacker can obtain a handle to window.parent.electronAPI via XSS and call the runCommand method of the IPC, the ipcMain process can execute arbitrary system commands with the current user's privileges. This vulnerability is fixed in 2.1.48.

Title
LobeHub has an unauthenticated authentication bypass on `webapi` routes via forgeable `X-lobe-chat-auth` header
Summary
LobeHub is a work-and-lifestyle space to find, build, and collaborate with agent teammates that grow with you. Prior to 2.1.48, the webapi authentication layer trusts a client-controlled X-lobe-chat-auth header that is only XOR-obfuscated, not signed or otherwise authenticated. Because the XOR key is hardcoded in the repository, an attacker can forge arbitrary auth payloads and bypass authentication on protected webapi routes. Affected routes include /webapi/chat/[provider], /webapi/models/[provider], /webapi/models/[provider]/pull, and /webapi/create-image/comfyui. This vulnerability is fixed in 2.1.48.

"value": "LobeHub is a work-and-lifestyle space to find, build, and collaborate with agent teammates that grow with you. Prior to 2.1.48, the webapi authentication layer trusts a client-controlled X-lobe-chat-auth header that is only XOR-obfuscated, not signed or otherwise authenticated. Because the XOR key is hardcoded in the repository, an attacker can forge arbitrary auth payloads and bypass authentication on protected webapi routes. Affected routes include /webapi/chat/[provider], /webapi/models/[provider], /webapi/models/[provider]/pull, and /webapi/create-image/comfyui. This vulnerability is fixed in 2.1.48."
