Name of the Vulnerable Software and Affected Versions W4 Post List WordPress plugin versions prior to 2.4.6

Description The issue arises from the plugin's failure to 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 2.4.6, update to version 2.4.6 or later to resolve the issue. As a temporary workaround, consider restricting the use of the vulnerable block options to minimize the risk of exploitation.
