{"id":"CVE-2026-62945","summary":"TREK: Cross-trip reservation title disclosure via file links","details":"TREK is a collaborative travel planner. Prior to 3.1.3, TREK file upload, update, and link actions accept attacker-controlled reservation_id, place_id, and assignment_id values without using findForeignLinkTarget() to verify that the referenced object belongs to the file's trip. An authenticated user with file-edit permission on any accessible trip can submit a foreign reservation identifier through POST /api/trips/:tripId/files/:id/link, POST /api/trips/:tripId/files, or PUT /api/trips/:tripId/files/:id. Subsequent reads through FILE_SELECT or getFileLinks() join the foreign reservation and return reservation_title, disclosing reservation existence and titles across private trip boundaries. This issue is fixed in version 3.1.3.","aliases":["GHSA-r4cp-666p-8f69"],"modified":"2026-08-23T03:42:48.831961461Z","published":"2026-08-20T21:51:19.844Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/62xxx/CVE-2026-62945.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-639"]},"references":[{"type":"WEB","url":"https://github.com/liketrek/TREK/releases/tag/v3.1.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/62xxx/CVE-2026-62945.json"},{"type":"ADVISORY","url":"https://github.com/liketrek/TREK/security/advisories/GHSA-r4cp-666p-8f69"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-62945"},{"type":"FIX","url":"https://github.com/liketrek/TREK/commit/03cdb4d27689922460ba87085d04b426d4d40d26"},{"type":"FIX","url":"https://github.com/liketrek/TREK/pull/1324"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/liketrek/trek","events":[{"introduced":"0"},{"fixed":"03cdb4d27689922460ba87085d04b426d4d40d26"},{"fixed":"0631e34a799c011a0cecc5e1d9bbff21a4ef9c0b"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"3.1.3"}]}}],"versions":["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-2026-62945.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:L/I:N/A:N"}]}
