The WP Photo Album Plus plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'HTTP_X_FORWARDED_FOR' parameter in all versions up to, and including, 9.2.08.003 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The nonce failure path for the getshortcodedrenderedfenodelay action serves as the log-write trigger rather than an access barrier — a deliberately failed nonce check causes wppa_log() to record the attacker-supplied X-Forwarded-For value to disk, making the exploit fully reachable by unauthenticated callers via the wp_ajax_nopriv_wppa endpoint.
