Name of the Vulnerable Software and Affected Versions The Post Grid Combo – 36+ Gutenberg Blocks plugin for WordPress versions up to, and including, 2.2.64

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

Recommendations For versions up to, and including, 2.2.64, update to a version higher than 2.2.64 to resolve the issue. As a temporary workaround, consider restricting access to the custom JS parameter to minimize the risk of exploitation.
