WordPress Plugin Vulnerabilities
Photo Gallery – GT3 Image Gallery & Gutenberg Block Gallery < 2.7.7.30 - Authenticated (Author+) Stored Cross-Site Scripting
Description
The Photo Gallery – GT3 Image Gallery & Gutenberg Block Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.7.7.29 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
