Name of the Vulnerable Software and Affected Versions The Ultimate Blocks WordPress plugin versions prior to 3.1.9

Description The issue is related to the Ultimate Blocks WordPress plugin, which does not validate and escape some of its block options before outputting them back in a page or post where the block is embedded. This could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.

Recommendations For versions prior to 3.1.9, update to version 3.1.9 or later to resolve the issue. As a temporary workaround, consider restricting the contributor role and above from accessing the affected block options until a patch is available. Restrict access to the vulnerable block options to minimize the risk of exploitation.
