CVE-2024-0893
The Schema App Structured Data plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the MarkupUpdate function in all versions up to, and including, 2.2.0.
Does this matter?
Lower severity and a low EPSS score (0.34%). Track it; it rarely justifies an emergency change on its own.
