CVE-2025-58807
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCross-Site Request Forgery (CSRF) vulnerability in Dsingh Purge Varnish Cache purge-varnish allows Stored XSS.This issue affects Purge Varnish Cache: from n/a through <= 2.6.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceCSRF vulnerability in the Purge Varnish Cache plugin allows authenticated administrators to be tricked into performing unintended actions that result in stored XSS. Attackers can exploit this by crafting malicious requests that inject persistent scripts into the application, which then execute when other users access the affected content.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Purge Varnish Cache plugin is installedCheck for the plugin directory in wp-content/plugins/ or view the installed plugins list in the WordPress admin under Plugins > Installed PluginsAffected if the plugin appears in the list of installed WordPress plugins
-
Locate the plugin version numberOpen the main plugin file (usually purge-varnish-cache.php or similar) and look for the Version header in the plugin comment block, or check the version field in the WordPress plugins admin listAffected if the version cannot be determined or is not listed as patched
-
Confirm admin access is availableVerify that administrator accounts exist and have access to the WordPress admin dashboard where the plugin settings are exposedAffected if administrators can access the plugin configuration interface
-
Check for state-changing plugin actionsExamine the plugin files for form actions or AJAX endpoints that modify settings, clear cache, or update configuration without anti-CSRF token validationAffected if the plugin performs actions (like saving settings or purging cache) without verifying request origin
-
Inspect input handling for stored contentReview plugin code for any functionality that stores user-supplied data to the database or displays content back to users (such as custom headers, URLs, or cache tags)Affected if the plugin stores or displays data without sanitization, allowing injection of malicious scripts
Your environment is affected if the Purge Varnish Cache plugin is installed, administrators can access its settings, and the plugin lacks CSRF protection on state-changing actions combined with insufficient input sanitization that could allow stored XSS injection.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement anti-CSRF tokens and proper referrer validation on all state-changing operations, and sanitize all user inputs/outputs to prevent XSS injection.
