Summary

CVE-2026-25649 is a high-severity CSRF (CWE-352) vulnerability in Traccar Traccar. Its CVSS base score is 7.3 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 3.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-3 (Access Enforcement).

Deeper analysis

CVE-2026-25649 is an open redirect vulnerability (CWE-601, CWE-352) in two OpenID Connect (OIDC)-related endpoints of the Traccar open-source GPS tracking system, affecting all versions up to and including 6.11.1. The flaw stems from a lack of validation for the `redirect_uri` parameter against a whitelist, enabling authenticated users to manipulate OAuth 2.0 authorization code redirects.

Authenticated attackers with low privileges can exploit this vulnerability remotely (AV:N) with low complexity (AC:L), though it requires user interaction (UI:R). By controlling the `redirect_uri`, they can steal authorization codes and redirect them to attacker-controlled URLs, achieving account takeover on any OAuth-integrated application and resulting in high confidentiality and integrity impacts (CVSS:3.1 score of 7.3; C:H/I:H/A:N/S:U).

The primary advisory, published on GitHub at https://github.com/traccar/traccar/security/advisories/GHSA-ccc7-4r59-4pp7 on 2026-02-23, describes the issue but notes that as of the time of publication, it is unclear whether a fix is available. Security practitioners should monitor for updates and consider restricting authenticated access or disabling OIDC endpoints until mitigation is confirmed.

Why these techniques?

Open redirect in public OIDC endpoints (T1190) directly enables theft of OAuth authorization codes leading to access tokens (T1528) and subsequent account takeover.
