Oct 11, 2026ngx_cache_purge before 3.0.4 can allow file deletion via a symlink attack in certain situations where nginx and a served application (e.g., WordPress) run underCVE-2026-108981 · WordPress plugins & themes · reported by MITRELow 3.6
ngx_cache_purge before 3.0.4 can allow file deletion via a symlink attack in certain situations where nginx and a served application (e.g., WordPress) run under the same user account. The attacker must be able to create a symlink inside the cache path. Version 3.0.4 fixes this for the case of a symlink created at an arbitrary earlier time, but does not resolve an applicable TOCTOU race condition. (The ngx_cache_purge module follows symlinks while walking the cache directory tree during purge operations. The module relies on nginx's ngx_walk_tree(), which relies on stat() and therefore follows symlinks.)
- Fixed in
- 3.0.4
- What to do
- Update the plugin to 3.0.4 or newer.
Oct 1, 2026Cache Enabler: Does not validate a URL before using it to build a filesystem path in its cache purge routineCVE-2026-19253 · WordPress plugins & themes · reported by WPScanHigh 8.7
The Cache Enabler WordPress plugin before 1.8.17 does not validate a URL before using it to build a filesystem path in its cache purge routine, and does not confine the resulting deletion to the cache directory, allowing unauthenticated users to delete arbitrary files and directories on sites where another installed Cache Enabler WordPress plugin before 1.8.17 or passes a request-derived URL to its public cache-clearing hook.

Jul 16, 2026The Cache Purger: Authorization bypassCVE-2026-15350 · WordPress plugins & themes · reported by WordfenceMedium 4.3
The The Cache Purger plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.3.20. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to permanently truncate the plugin's cache-purge audit log (wp-content/purge.log), destroying the entire cache-purge audit history. The tcp_log_purge nonce is rendered in the admin bar on frontend pages accessible to all authenticated users including subscribers, meaning any authenticated user possesses the nonce required to trigger the deletion.

Jul 22, 2025Nginx Cache Purge Preload: Remote Code ExecutionCVE-2025-6213 · WordPress plugins & themes · reported by WordfenceHigh 7.2
The Nginx Cache Purge Preload plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.1.1 via the 'nppp_preload_cache_on_update' function.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
