CVE-2026-44314

Traccar 5.7 through 6.16.0 contains a cross-site request forgery vulnerability that allows attackers to log victims into attacker-controlled accounts because the OpenID Connect callback never validates the OAuth state parameter. Attackers can induce a victim's browser to load /api/session/openid/callback with their own authorization code, causing data the victim enters, such as registered devices, to land in the attacker's account.

Traccar through 6.16.0 contains a weak password recovery vulnerability that allows attackers to reuse password reset tokens as session credentials because TokenManager does not bind tokens to a purpose. Attackers holding a leaked reset link can obtain a full session via /api/session or change passwords via /api/password/update, retaining access for seven days even after the victim resets their password.

Traccar is an open source GPS tracking system. Prior to 6.14.0, an authenticated user with permission to manage groups and request reports can create a cyclic group-parent hierarchy and request a trips or stops report for a device in that hierarchy. GroupResource permits the parent cycle, while AttributeUtil.lookup follows group parents without cycle detection, a visited set, or a depth limit, causing the lookup to never terminate, pinning a Jetty worker at high CPU and potentially exhausting the web/API worker pool when requests are repeated.

In Traccar 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. Validation checks only the first two keys, but removePermission() concatenates every map key into the SQL WHERE clause as column identifiers, enabling SQL injection and extraction of arbitrary database values, including administrator email, password hashes, and salts. The issue is fixed in 6.14.0.

Traccar versions 6.1-6.8.1 (default installs) and 5.8-6.0 (non-default installs with web.override enabled) are vulnerable to unauthenticated local file inclusion attacks, which can lead to leakage of passwords or any file on the filesystem, including the Traccar configuration file. The vulnerable code is removed in version 6.9.0.
