CVE-2026-42456: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in Mintplex-Labs anything-llm
CVE-2026-42456 is an insecure direct object reference (IDOR) vulnerability in Mintplex-Labs' AnythingLLM application prior to version 1. 12. 1. The vulnerability allows an authenticated user to access another user's private text-to-speech chat responses by exploiting insufficient authorization checks on the GET /api/workspace/:slug/tts/:chatId endpoint. The endpoint validates workspace membership but does not verify ownership of the specific chat resource, exposing sensitive audio content. This issue has been patched in version 1. 12. 1. The vulnerability has a CVSS score of 4. 3, indicating medium severity, and no known exploits in the wild have been reported.
AI Analysis
Technical Summary
AnythingLLM versions before 1.12.1 contain an IDOR vulnerability in the text-to-speech (TTS) API endpoint. The GET /api/workspace/:slug/tts/:chatId route returns audio responses for chats within a workspace but fails to enforce ownership validation on the chatId parameter. As a result, any authenticated user with workspace access can retrieve private audio responses of other users if they know or guess the chatId. This exposure of sensitive information is classified under CWE-200 (Exposure of Sensitive Information) and CWE-639 (Authorization Bypass Through User-Controlled Key). The vulnerability was fixed in version 1.12.1.
Potential Impact
An authenticated user within the same workspace can access private assistant responses of other users in audio form, potentially leading to unauthorized disclosure of sensitive information. The impact is limited to confidentiality, with no integrity or availability effects reported. The vulnerability requires authentication and knowledge or guessing of chat IDs, reducing exploit complexity. No known active exploitation has been reported.
Mitigation Recommendations
This vulnerability has been addressed in AnythingLLM version 1.12.1. Users and administrators should upgrade to version 1.12.1 or later to remediate this issue. Since the product is not a cloud service, patching the affected software is necessary. Patch status is confirmed by the vendor advisory indicating the fix in version 1.12.1. No additional mitigation steps are indicated.
