CVE-2025-0856
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 · uneditedThe PGS Core plugin for WordPress is vulnerable to unauthorized access, modification, and loss of data due to a missing capability check on multiple functions in all versions up to, and including, 5.8.0. This makes it possible for unauthenticated attackers to add, modify, or plugin options.
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 · moderate confidenceThe PGS Core WordPress plugin up to version 5.8.0 lacks capability checks on multiple functions, allowing unauthenticated attackers to add, modify, or delete plugin options via direct API calls. This broken access control vulnerability enables complete control over plugin settings without any authentication.

dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify PGS Core plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'PGS Core' in the list, or check the plugins directory via file system for /wp-content/plugins/pgs-core/Affected if PGS Core plugin is present in the WordPress installation
-
Check installed version numberIn WordPress admin, find PGS Core in the Plugins list and read the version number displayed below the plugin name. Alternatively, check the main plugin file header in /wp-content/plugins/pgs-core/ for the 'Version' tagAffected if Version is 5.8.0 or lower (any version below 5.8.1)
-
Confirm plugin is activeIn WordPress admin Plugins page, verify that PGS Core shows as 'Active' under the plugin statusAffected if Plugin is active and version is 5.8.0 or lower

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.
dbcve · scopedUpdate to version 5.8.1 or later which includes proper capability checks. If no update is available, disable the plugin until a patched version is released.
Upgrade to PGS Core version 5.8.1 or later (the first version containing the security fix)
- 1. Log in to the WordPress admin dashboard
- 2. Navigate to Plugins > Installed Plugins
