Description

This module enables you to add dynamic caption support to PhotoSwipe image galleries. The module doesn't sufficiently sanitize user-supplied input (such as image alt tags) in its dynamic caption script, leading to a Cross-Site Scripting (XSS) vulnerability. This vulnerability is mitigated by the fact that an attacker must have a role that permits them to enter HTML content.
