The fix

We hold no Microsoft remediation data for CVE-2026-52851, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.

What it is

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.
