CVE-2026-33920 (GCVE-0-2026-33920)

Vulnerability from cvelistv5 – Published: 2026-09-08 13:57 – Updated: 2026-09-08 14:20

Title

Cross-site request forgery in the Guardian/CMC login before 26.3.0

Summary

A cross-site request forgery vulnerability was discovered in the login functionality (both standard and SAML) due to missing validation of the anti-CSRF token. An attacker with a valid account can trick a victim into unknowingly authenticating with the attacker's credentials. Any operation performed by the victim in this state is attributed to the attacker's account, compromising the integrity of the audit trail.
