{"id":"CVE-2026-59816","state":"PUBLISHED","title":"Joplin: Path traversal in transcribe proxy endpoint via URL-encoded slash","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.","publishedAt":"2026-09-21T20:54:39.684Z","updatedAt":"2026-09-22T13:30:48.089Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["laurent22 joplin"],"affected":[{"vendor":"laurent22","product":"joplin","versions":[{"version":"< 3.7.7","status":"affected"}]}],"references":["https://github.com/laurent22/joplin/security/advisories/GHSA-r7wp-3494-fwf4","https://github.com/laurent22/joplin/commit/d97a5091a35c2923984d3777320500b594afcdce"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/59xxx/CVE-2026-59816.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-59816","state":"PUBLISHED","datePublished":"2026-09-21T20:54:39.684Z","dateUpdated":"2026-09-22T13:30:48.089Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-07T15:00:50.978Z"},"containers":{"cna":{"title":"Joplin: Path traversal in transcribe proxy endpoint via URL-encoded slash","descriptions":[{"lang":"en","value":"Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks.
