CVE-2024-4268

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 arises from insufficient input sanitization and output escaping on user-supplied attributes in the plugin's blocks, allowing authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages. These scripts will execute whenever a user accesses an injected page.

Recommendations For versions up to and including 3.1.9, update to a version that addresses the insufficient input sanitization and output escaping issue to prevent stored cross-site scripting attacks.
