{"cve":"CVE-2026-77320","nvd":{"published":"2026-09-24T19:17:16.730","modified":"2026-09-29T04:17:58.450","status":"Deferred","description":"TREK is a collaborative travel planner. Prior to 3.3.0, getSharedTripData in server/src/services/shareService.ts returns days, assignments, dayNotes, and places through GET /api/shared/:token even when the trip owner disables share_map. The client hides the map, but the public JSON response still includes the itinerary and place names, coordinates, addresses, descriptions, notes, and prices. Anyone holding the valid share token can therefore read location and route information that the owner explicitly chose not to share, although the random token remains required and the flaw does not permit modification. This issue is fixed in version 3.3.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-200","CWE-284","CWE-602"],"references":["https://github.com/liketrek/TREK/commit/19064b39176660f3be3a2df198c87949504046e2","https://github.com/liketrek/TREK/pull/1520","https://github.com/liketrek/TREK/releases/tag/v3.3.0","https://github.com/liketrek/TREK/security/advisories/GHSA-9hc8-p7gm-p7mx","https://github.com/liketrek/TREK/security/advisories/GHSA-9hc8-p7gm-p7mx"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-77320","score":0.00291,"percentile":0.21691,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
