Name of the Vulnerable Software and Affected Versions Fast Velocity Minify versions prior to 3.5.1

Description The Fast Velocity Minify plugin for WordPress is susceptible to Stored Cross-Site Scripting through admin settings. Insufficient input sanitization and output escaping allow authenticated attackers with administrator-level permissions or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses the injected page. This issue specifically impacts multi-site installations and those where unfiltered html has been disabled.

Recommendations Update Fast Velocity Minify to a version later than 3.5.1.
