CVE-2026-25649
Versions of the Traccar open-source GPS tracking system up to and including 6.11.1 contain an issue in which authenticated users can steal OAuth 2.0 authorization codes by exploiting an open redirect vulnerability in two OIDC-related endpoints.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Versions of the Traccar open-source GPS tracking system up to and including 6.11.1 contain an issue in which authenticated users can steal OAuth 2.0 authorization codes by exploiting an open redirect vulnerability in two OIDC-related endpoints. The `redirect_uri` parameter is not validated against a whitelist, allowing attackers to redirect authorization codes to attacker-controlled URLs, enabling account takeover on any OAuth-integrated application. As of time of publication, it is unclear whether a fix is available.
