{"schema":"threatline.record/2","record":{"id":"CVE-2026-77293","aliases":["GHSA-cjc5-722j-vvmf"],"summary":"TREK: Cross-user note-file deletion (IDOR / Broken Access Control)","details":"TREK is a collaborative travel planner. Prior to 3.3.0, the DELETE /api/trips/:tripId/collab/notes/:noteId/files/:fileId endpoint authorizes an authenticated user against the attacker-controlled tripId but deleteNoteFile in server/src/services/collabService.ts resolves the target only by note and file identifiers without requiring the file to belong to that trip. A user with edit access to any trip can submit identifiers belonging to another user's trip and permanently delete that note-file attachment. Sequential identifiers make broad targeting practical, while attachment read operations remain trip-scoped and are not affected. This issue is fixed in version 3.3.0.","categories":["Unclassified"],"product":"TREK","vendor":"mauriceboe","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-77293","source_modified_at":"2026-09-24T18:45:45.240Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"TREK","vendor":"mauriceboe","versions":[{"status":"affected","version":"< 3.3.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/liketrek/TREK/security/advisories/GHSA-cjc5-722j-vvmf","source_modified_at":"2026-08-20T19:24:33Z","fetched_at":"2026-10-24T05:41:33.294140Z","package":{"ecosystem":"other","name":"mauriceboe/TREK"},"range":"<= 3.1.4"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/liketrek/TREK/security/advisories/GHSA-cjc5-722j-vvmf","source_modified_at":"2026-08-20T19:24:33Z","fetched_at":"2026-10-24T05:41:33.294140Z","package":{"ecosystem":"other","name":"mauriceboe/TREK"},"version":"3.3.0"}],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.0038,"percentile":0.30834,"score_date":"2026-10-23"},"published_at":"2026-09-24T18:08:30.599Z","modified_at":"2026-09-24T18:45:45.240Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-77293","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-24T18:45:45.240Z"},{"source":"GitHub Advisory Database","url":"https://github.com/liketrek/TREK/security/advisories/GHSA-cjc5-722j-vvmf","fetched_at":"2026-10-24T05:41:33.294140Z","source_modified_at":"2026-08-20T19:24:33Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-77293","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/liketrek/TREK/security/advisories/GHSA-cjc5-722j-vvmf","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/liketrek/TREK/pull/1520","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/liketrek/TREK/commit/19064b39176660f3be3a2df198c87949504046e2","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/liketrek/TREK/releases/tag/v3.3.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-24T18:44:45.227942Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-24T18:45:45.240Z","content_hash":"e4af870f097ac53d85fa53bc0457210c38c4ad774fee84e08fbf6df3446d517c"}}
