CVE-2026-46437 · Severity: medium · CVSS 4.8 · Published 2026-10-07

wger is a free workout and nutrition tracking application. A vulnerability allows attackers who steal a user's API credentials (bearer tokens) to retain access even after the victim logs out or changes their password. An attacker with a stolen token can read private fitness data and modify workout records indefinitely until the token naturally expires or is manually revoked.

Technologies: wger (PyPI), Wger. Vendors: PyPI, Wger.

Technical details

The vulnerability exists in wger's authentication lifecycle: logout via the `/user/logout` endpoint only clears the Django session cookie and does not revoke DRF authtokens or JWT refresh tokens. Similarly, password changes do not invalidate existing API credentials—DRF tokens remain in the database unchanged, and JWT refresh tokens lack server-side revocation. An attacker with a stolen bearer token can continue to access protected `/api/v2/*` endpoints and refresh access tokens until token expiry or manual rotation.
