CVE-2026-42456: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in Mintplex-Labs anything-llm
AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. Prior to version 1.12.1, GET /api/workspace/:slug/tts/:chatId in AnythingLLM returns the text-to-speech audio for another user's chat response within the same workspace because the route validates workspace membership but does not enforce ownership of the targeted chat row. As a result, an authenticated user can access another user's private assistant response in audio form if the chatId is known or guessed. This constitutes an insecure direct object reference (IDOR) affecting private chat response content exposed through the TTS endpoint. This issue has been patched in version 1.12.1.
AI Analysis
Technical Summary
AnythingLLM's GET /api/workspace/:slug/tts/:chatId endpoint validates workspace membership but fails to enforce ownership of the targeted chat resource. Consequently, an authenticated user can retrieve audio content of another user's private assistant chat response if they know or can guess the chatId. This constitutes an insecure direct object reference (IDOR) vulnerability classified under CWE-200 (Exposure of Sensitive Information) and CWE-639 (Authorization Bypass Through User-Controlled Key). The vulnerability affects versions prior to 1.12.1 and has been patched in that release.
Potential Impact
An authenticated user within the same workspace can access private audio chat responses of other users, leading to unauthorized disclosure of sensitive information. There is no impact on data integrity or system availability. The CVSS v3.1 base score is 4.3 (medium severity), reflecting the limited scope and impact of the information exposure.
Mitigation Recommendations
This vulnerability has been patched in AnythingLLM version 1.12.1. Users and administrators should upgrade to version 1.12.1 or later to remediate this issue. No additional mitigation steps are indicated by the vendor advisory.
