{"id":"CVE-2026-59816","published":"2026-09-21T21:17:06.490","lastModified":"2026-09-21T21:17:06.490","description":"Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Prior to 3.7.7, the GET /api/transcribe/:id and POST /api/transcribe/:id handlers in packages/server/src/routes/api/transcribe.ts on Joplin Server instances with TRANSCRIBE_ENABLED=true pass the decoded id directly into transcription backend URLs. An authenticated user can place URL-encoded slash and parent-directory segments in the job ID, causing parseSubPath() to decode a path that escapes the intended /transcribe/ prefix. The server then proxies the request to other transcription-backend endpoints and can return their responses, potentially exposing internal administrative, health, or configuration data. This issue is fixed in version 3.7.7.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://github.com/laurent22/joplin/commit/d97a5091a35c2923984d3777320500b594afcdce","tags":[]},{"url":"https://github.com/laurent22/joplin/security/advisories/GHSA-r7wp-3494-fwf4","tags":[]}],"exploitRefs":[{"url":"https://github.com/laurent22/joplin/commit/d97a5091a35c2923984d3777320500b594afcdce","tags":[]},{"url":"https://github.com/laurent22/joplin/security/advisories/GHSA-r7wp-3494-fwf4","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows an authenticated user to exploit URL-encoded slashes and parent-directory segments in job IDs to access internal transcription-backend endpoints, potentially exposing sensitive data.","exploitability":"Exploitation requires authentication and knowledge of specific URL patterns; difficult but feasible with proper reconnaissance.","blast_radius":"If exploited, it could lead to exposure of internal administrative or configuration data accessible by authenticated users.","remediation":"Update Joplin Server instances to version 3.7.7 or later to mitigate the risk.","tags":["auth-required","data-exposure","web"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-22T06:33:45.804Z"}}
