CVE-2024-43927Network attack vector

Page-cache flushing via missing nonce validation

Published Jan 2, 2025 · Updated Apr 28, 2026

Cross-site request forgery in Till Krüss Email Address Encoder 1.0.23 and earlier allows remote attackers to flush page caches. The eae_clear_caches() function processes a cache-flush request without validating a WordPress nonce before invoking supported cache plugins. Exploitation requires an authenticated site administrator to follow a crafted link, causing cache eviction and performance degradation rather than deletion of site content or configuration.
