Name of the Vulnerable Software and Affected Versions The Ultimate Blocks – WordPress Blocks Plugin versions up to, and including, 3.1.9

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

Recommendations For versions up to, and including, 3.1.9, update to a version higher than 3.1.9 to resolve the issue. As a temporary workaround, consider restricting access to the title tag parameter to minimize the risk of exploitation.
