{"id":"CVE-2026-77293","published":"2026-09-24T19:17:16.397","lastModified":"2026-09-25T13:17:26.220","description":"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.","cvssScore":7.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","cwes":["CWE-639","CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/liketrek/TREK/commit/19064b39176660f3be3a2df198c87949504046e2","tags":[]},{"url":"https://github.com/liketrek/TREK/pull/1520","tags":[]},{"url":"https://github.com/liketrek/TREK/releases/tag/v3.3.0","tags":[]},{"url":"https://github.com/liketrek/TREK/security/advisories/GHSA-cjc5-722j-vvmf","tags":[]},{"url":"https://github.com/liketrek/TREK/security/advisories/GHSA-cjc5-722j-vvmf","tags":[]}],"exploitRefs":[{"url":"https://github.com/liketrek/TREK/commit/19064b39176660f3be3a2df198c87949504046e2","tags":[]},{"url":"https://github.com/liketrek/TREK/pull/1520","tags":[]},{"url":"https://github.com/liketrek/TREK/releases/tag/v3.3.0","tags":[]},{"url":"https://github.com/liketrek/TREK/security/advisories/GHSA-cjc5-722j-vvmf","tags":[]},{"url":"https://github.com/liketrek/TREK/security/advisories/GHSA-cjc5-722j-vvmf","tags":[]}],"hasPoc":true,"ai":null}
