Name of the Vulnerable Software and Affected Versions The Ultimate Blocks – WordPress Blocks Plugin versions up to, and including, 3.2.7

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

Recommendations For versions up to, and including, 3.2.7, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the buttonTextColor parameter to minimize the risk of exploitation.
