{"id":"CVE-2026-77293","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.","aliases":["GHSA-cjc5-722j-vvmf"],"modified":"2026-09-27T03:30:22.248376793Z","published":"2026-09-24T18:08:30.599Z","database_specific":{"cwe_ids":["CWE-639","CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77293.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/liketrek/TREK/releases/tag/v3.3.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77293.json"},{"type":"ADVISORY","url":"https://github.com/liketrek/TREK/security/advisories/GHSA-cjc5-722j-vvmf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77293"},{"type":"FIX","url":"https://github.com/liketrek/TREK/commit/19064b39176660f3be3a2df198c87949504046e2"},{"type":"FIX","url":"https://github.com/liketrek/TREK/pull/1520"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/liketrek/trek","events":[{"introduced":"0"},{"fixed":"19064b39176660f3be3a2df198c87949504046e2"},{"fixed":"f9c992ec9363301762ac00e97747c1dd0fe37d6b"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.3.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["plugin-sdk-v1.3.1","v3.2.1","plugin-sdk-v1.3.0","v3.2.0","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.22","v3.0.21","v3.0.20","v3.0.19","v3.0.18","v3.0.17","v3.0.16","v3.0.15","v3.0.14","v3.0.13","v3.0.12","v3.0.11","v3.0.10","v3.0.9","v3.0.8","v3.0.7","v3.0.6","v3.0.5","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v2.9.14","v2.9.13","v2.9.12","v2.9.11","v2.9.10","v2.9.9","v2.9.8","v2.9.7","v2.9.6","v2.9.5","v2.9.4","v2.9.2","v2.8.4","v2.8.0","v2.7.2","v2.7.0","v2.6.2","v2.6.1","v2.6.0","v2.5.7","v2.5.6","v2.5.5","v2.5.4","v2.5.2","v2.5.1","v2.5.0","v2.4.0","v2.3.5","v2.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-77293.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L"}]}
