Name of the Vulnerable Software and Affected Versions The Photo Gallery – GT3 Image Gallery & Gutenberg Block Gallery plugin for WordPress versions up to, and including, 2.7.7.21

Description The issue is related to Stored Cross-Site Scripting via image alt text due to insufficient input sanitization and output escaping. This allows authenticated attackers with author-level access and above to inject arbitrary web scripts in pages, which will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 2.7.7.21, update to a version that addresses the insufficient input sanitization and output escaping issue to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to image alt text editing to minimize the risk of exploitation.
