CVE-2021-24329
The WP Super Cache WordPress plugin before 1.7.3 did not properly sanitise its wp_cache_location parameter in its settings, which could lead to a Stored Cross-Site Scripting issue.
Does this matter?
Lower severity and a low EPSS score (4.46%). Track it; it rarely justifies an emergency change on its own.
