Summary

The Envira Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the gallery 'description' configuration field in all versions up to and including 1.12.4 due to insufficient input sanitization and output escaping. This allows authenticated attackers with Author-level access or above to inject arbitrary web scripts that execute whenever a user accesses a page displaying the gallery with a description enabled.

Risk Assessment

An attacker can inject malicious scripts that execute in visitors' browsers, potentially leading to data theft, session hijacking, or malware distribution.

Recommendation

Update the Envira Gallery plugin to the latest patched version. Additionally, restrict gallery editing permissions to trusted users only.
