نطاق الضرر
If the affected endpoint is reachable, a crafted link may execute attacker-controlled script in a victim's browser under the SPIP site's origin. The practical impact depends on authentication state, cookie flags, administrative exposure, and what sensitive actions or data the SPIP origin can reach.
