CVE-2026-16296: Unknown Clearfy Cache

Medium severity, CVSS 4.7. EPSS: 0.3% chance of exploitation in the next 30 days.

The Clearfy Cache WordPress plugin before 2.4.3 does not validate the redirect target in its Cyrlitera old-URL redirect handler, passing a decoded request URI to an unsafe redirect function, which allows unauthenticated attackers to redirect visitors to an arbitrary external URL when a non-default option is enabled.

Affected products

  • Unknown Clearfy Cache: before 2.4.3 (fixed in 2.4.3)
