{"cve":"CVE-2026-42456","nvd":{"published":"2026-05-08T23:16:39.230","modified":"2026-07-24T21:10:00.143","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-639","CWE-200"],"references":["https://github.com/Mintplex-Labs/anything-llm/commit/4f3f77119d342e5489d1ba7533ad6d51bdcd565f","https://github.com/Mintplex-Labs/anything-llm/releases/tag/v1.12.1","https://github.com/Mintplex-Labs/anything-llm/security/advisories/GHSA-jwqg-jfg3-x5vv","https://github.com/Mintplex-Labs/anything-llm/security/advisories/GHSA-jwqg-jfg3-x5vv"],"products":["mintplexlabs:anythingllm"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-42456","score":0.00301,"percentile":0.22881,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
