Technical details

A Spring Expression Language (SpEL) injection vulnerability exists in ReplyNotificationSubscriptionHelper.java where user-supplied email addresses from guest comments are interpolated directly into SpEL expression strings without escaping. An attacker can inject SpEL operators (e.g., via email "a'||true||'a@example.com") to create an expression that always evaluates to true, matching all comment reply notifications regardless of intended recipient. The vulnerability requires guest comments enabled and reply notification configuration; exploitation is unauthenticated and remotely triggerable.
