Title
Pachno 1.0.6 Authentication Bypass via runSwitchUser()
Summary
Pachno 1.0.6 contains an authentication bypass vulnerability in the runSwitchUser() action that allows authenticated low-privilege users to escalate privileges by manipulating the original_username cookie. Attackers can set the client-controlled original_username cookie to any value and request a switch to user ID 1 to obtain session tokens or password hashes belonging to administrator accounts.

Title
TypeBot: Cross-Workspace Credential Theft via Bot-Engine Preview Endpoint
Summary
TypeBot is a chatbot builder tool. In versions 3.15.2 and prior, the fix for GHSA-4xc5-wfwc-jw47 ("Credential Theft via Client-Side Script Execution and API Authorization Bypass") is incomplete. While the builder's getCredentials tRPC endpoint was patched with workspace membership checks, the bot-engine runtime still allows any authenticated user to use credentials from any workspace via the preview chat endpoint. The bot-engine's getCredentials() utility function uses a falsy check (if (workspaceId && ...)) for workspace ownership validation. Since the preview endpoint accepts a client-controlled workspaceId field and the Zod schema allows empty strings, an attacker can supply workspaceId: "" to bypass credential ownership verification entirely. Exploitation can result in credential exfiltration, external service abuse, financial damage and a data breach.

Title
TypeBot: Cross-Typebot Result Data Access via Missing typebotId Filter
Summary
TypeBot is a chatbot builder tool. In versions 3.15.2 and prior, the bot engine's the findResult query does not filter results by typebotId, allowing an authenticated user to load result data (user answers, variable values) from a different typebot by supplying a foreign resultId to the startChat endpoint. Exploitation is constrained by CUID2's cryptographically random 24-character IDs (making brute-force infeasible), the requirement that rememberUser be enabled, and the need for matching variable names in the current typebot. If successfully exploited, an attacker can access the original user's previous answers, session variable values, and hasStarted flag, potentially exposing PII like names, emails, and phone numbers. This issue has been fixed in version 3.16.0.

Title
Directus has a Path Traversal and Broken Access Control in File Management API
Summary
Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.17.0, the PATCH /files/{id} endpoint accepts a user-controlled filename_disk parameter. By setting this value to match the storage path of another user's file, an attacker can overwrite that file's content while manipulating metadata fields such as uploaded_by to obscure the tampering. This vulnerability is fixed in 11.17.0.

Title
Neko has Self-service Privilege Escalation for Authenticated Users
Summary
Neko is a a self-hosted virtual browser that runs in Docker and uses WebRTC In versions 3.0.0 through 3.0.10 and 3.1.0 through 3.1.1, any authenticated user can immediately obtain full administrative control of the entire Neko instance (member management, room settings, broadcast control, session termination, etc.). This results in a complete compromise of the instance. The vulnerability has been patched in v3.0.11 and v3.1.2. If upgrading is not immediately possible, the following mitigations can reduce risk: Restrict access to trusted users only (avoid granting accounts to untrusted parties); ensure all user passwords are strong and only shared with trusted individuals; run the instance only when needed; avoid leaving it continuously exposed; place the instance behind authentication layers such as a reverse proxy with additional access controls; disable or restrict access to the /api/profile endpoint if feasible; and/or monitor for suspicious privilege changes or unexpected administrative actions. Note that these are temporary mitigations and do not fully eliminate the vulnerability. Upgrading is strongly recommended.

Mitigation
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Architecture and Design
Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
