Conditional Fields For Contact Form 7
Monthly
Denial-of-service condition in Conditional Fields for Contact Form 7 WordPress plugin allows remote unauthenticated attackers to crash PHP processes by injecting arbitrarily large iteration values through REST API parameters. The Wpcf7cfMailParser class processes user-supplied POST data without validation, enabling attackers to trigger unbounded loops with multiple regex operations that exhaust server memory. Affects all versions through 2.6.7 with vendor patch now available. EPSS data not provided, but the network-accessible unauthenticated attack vector (AV:N/PR:N) combined with low complexity (AC:L) indicates straightforward exploitation potential against publicly accessible WordPress sites running this plugin.
