CVE-2023-1930
Published: April 11, 2026
Official Description
The WP Fastest Cache plugin for WordPress is vulnerable to unauthorized data deletion due to a missing capability check on the wpfc_clear_cache_of_allsites_callback function in versions up to, and including, 1.1.2. This makes it possible for authenticated attackers with subscriber-level access to delete caches.
Technical Analysis
CVE-2023-1930 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2023-1930 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
