## Technical details

A Cross-Site Scripting (XSS) vulnerability exists in the Modula Image Gallery plugin for WordPress (versions up to and including 2.14.23) due to improper neutralization of input during web page generation (CWE-79). The flaw allows an authenticated attacker with 'Subscriber' privileges to inject arbitrary web scripts. Successful exploitation requires a victim (such as an administrator) to interact with the malicious payload, which then executes in the context of the victim's browser. This can lead to session hijacking, unauthorized data access, or site redirection. The issue is resolved in version 2.14.24.
