CSRF in InterServer Mail Baby SMTP 2.8 and earlier allows remote attackers to trigger unauthorized WordPress administrative actions. The plugin's settings and test-email request handlers accept state-changing requests without consistent nonce verification or capability checks. Exploitation requires a logged-in administrator to visit or submit attacker-controlled content; published sources do not identify the exact setting or test-email action changed.
