CVE-2021-24209: WP Super Cache < 1.7.2 - Authenticated Remote Code Execution (RCE)

• Severity: high (CVSS 7.2 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 27.7% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2021-04-05 · updated 2026-06-17
• Weakness: CWE-94

Description

The WP Super Cache WordPress plugin before 1.7.2 was affected by an authenticated (admin+) RCE in the settings page due to input validation failure and weak $cache_path check in the WP Super Cache Settings -> Cache Location option. Direct access to the wp-cache-config.php file is not prohibited, so this vulnerability can be exploited for a web shell injection.

Affected products

• WP Super Cache: before 1.7.2 — fixed in 1.7.2

How to fix

Upgrade to a fixed version: WP Super Cache 1.7.2. Check the vendor advisory for mitigations.
