CVE-2024-4335
The Rank Math SEO with AI Best SEO Tools plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘textAlign’ parameter in versions up to, and including, 1.0.217 due to insufficient input sanitization and output escaping.
Does this matter?
Lower severity and a low EPSS score (0.43%). Track it; it rarely justifies an emergency change on its own.
Description
The Rank Math SEO with AI Best SEO Tools plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘textAlign’ parameter in versions up to, and including, 1.0.217 due to insufficient input sanitization and output escaping.
