CVE-2023-6645
The Post Grid Combo – 36+ Gutenberg Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the custom JS parameter in all versions up to, and including, 2.2.64 due to insufficient input sanitization and output escaping.
Does this matter?
Lower severity and a low EPSS score (0.34%). Track it; it rarely justifies an emergency change on its own.
