Privilege escalation via login-page request forgery
Published Dec 6, 2021 · Updated Aug 3, 2024
Cross-site request forgery in the b2evolution CMS 7.2.3 login page allows attackers to escalate privileges through a crafted request. The public record identifies the login page as the affected locus but does not disclose which request lacks CSRF validation or which privileged state it changes. Exploitation requires an authenticated user to submit an attacker-controlled request; the published evidence does not define the resulting privilege level.
