CVE-2026-100524
Cotonti through 1.0.0 contains a cross-site request forgery vulnerability in the extensions manager that allows attackers to perform state-changing actions without anti-CSRF token validation.
Does this matter?
Lower severity and a low EPSS score (0.12%). Track it; it rarely justifies an emergency change on its own.
