Summary

Traccar is an open source GPS tracking system. Prior to 6.14.0, an authenticated, non-readonly user with access to an object usable in a permission pair can submit DELETE /api/permissions with an extra attacker-controlled JSON key. Permission(LinkedHashMap<String, Long>) in src/main/java/org/traccar/model/Permission.java validates only the first two keys, but DatabaseStorage.removePermission() in src/main/java/org/traccar/storage/DatabaseStorage.java concatenates every map key into the SQL WHERE clause as a column identifier. The extra key therefore becomes attacker-controlled SQL and provides a blind boolean or error oracle that can extract arbitrary database values, including administrator email, password hashes, and salts, or conditionally delete permission rows. Unauthenticated requests are rejected. This issue is fixed in 6.14.0.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of traccar/traccar published their own advisory on GitHub. Reviewed sources take precedence over it.
