CVE-2025-9517
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 atec Debug plugin for WordPress is vulnerable to remote code execution in all versions up to, and including, 1.2.22 via the 'custom_log' parameter. This is due to insufficient sanitization when saving the custom log path. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute code on the server.
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 confidenceThe atec Debug WordPress plugin versions up to 1.2.22 contain an RCE vulnerability via the 'custom_log' parameter. Authenticated administrators can supply a malicious log path that, due to insufficient sanitization during save operations, allows arbitrary code execution on the server.

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.
-
Confirm atec Debug plugin is installedIn WordPress admin, navigate to Plugins > Installed Plugins and look for 'atec Debug' in the list. Alternatively, check the /wp-content/plugins/ directory for a folder named 'atec-debug' or similar.Affected if The plugin is present in the WordPress installation
-
Identify installed plugin versionIn WordPress admin, click on the plugin name in the Plugins list to view its details, or check the plugin's main PHP file for the 'Version' header comment in the plugin metadata.Affected if The version is 1.2.22 or lower, or if the version cannot be determined (plugin may be outdated unmaintained)
-
Check for custom_log configuration accessNavigate to the plugin settings page in WordPress admin (typically under Tools > atec Debug or Settings > atec Debug) and look for any field labeled 'custom_log', 'Log Path', or similar that accepts a file path value.Affected if The plugin settings page exists and contains a configurable log path parameter that can be modified
-
Verify administrator role accessIn WordPress admin, go to Users > All Users and review which accounts have the Administrator role. Check if any unexpected or unauthorized administrator accounts exist.Affected if The WordPress site has administrator accounts, making the attack surface active for this authenticated vulnerability
-
Audit recent plugin activity logsCheck WordPress debug logs, server access logs, and any plugin-specific logs for suspicious entries involving the custom_log parameter or unusual file path references in the wp-content directory.Affected if Log entries show unexpected paths or suspicious parameter values submitted to the plugin
A WordPress site is affected if the atec Debug plugin version 1.2.22 or lower is installed and the administrator can access plugin settings containing the custom_log parameter field.

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 dataUpdate the atec Debug plugin to a version beyond 1.2.22 once available. Until patched, limit administrator account access and audit user activity for signs of exploitation.
