| Descripción | **Expression Language Injection via Guest Reply Subscription:**
- When guest comments are enabled, Halo creates a reply-notification subscription for an anonymous visitor.
- The visitor identity, which contains the submitted email address, is inserted directly into a Spring Expression Language (SpEL) expression.
- Single quotes in the identity are not escaped before the expression is stored and later evaluated. |
