CVE-2025-32633 Overview
CVE-2025-32633 is a path traversal vulnerability in the neoslab Database Toolset plugin for WordPress. The flaw affects all versions up to and including 1.8.4. An unauthenticated attacker can manipulate file path inputs to traverse outside the intended directory and delete arbitrary files on the server. The vulnerability maps to [CWE-22] Improper Limitation of a Pathname to a Restricted Directory. Successful exploitation enables arbitrary file deletion, which can lead to site takeover when critical WordPress files such as wp-config.php are removed.
Critical Impact
Unauthenticated attackers can delete arbitrary files on affected WordPress installations, disrupting site availability and potentially enabling full site compromise.
Affected Products
- neoslab Database Toolset plugin for WordPress
- All versions from initial release through 1.8.4
- WordPress installations with the plugin enabled

Technical Details for CVE-2025-32633
Vulnerability Analysis
The Database Toolset plugin fails to validate and sanitize user-supplied file path parameters before passing them to file deletion routines. Attackers can inject directory traversal sequences such as ../ to escape the plugin's intended working directory. This allows references to files anywhere on the filesystem accessible to the web server user. The exposure is reachable over the network without authentication or user interaction. Because the impact is restricted to file deletion, confidentiality and integrity of file contents are not directly affected, but availability is severely degraded.
Root Cause
The root cause is missing canonicalization and allowlist validation of pathname inputs handled by the plugin. The vulnerable code path accepts an attacker-controlled filename or path argument and resolves it relative to a base directory without rejecting traversal sequences. Functions that delete files act on the resolved path without verifying the target resides within an approved directory. This is a classic [CWE-22] pattern affecting WordPress plugins that expose file management features through admin-ajax endpoints or REST routes.
Attack Vector
Exploitation occurs over the network against the WordPress HTTP interface. The attacker sends a crafted request to the plugin endpoint that handles file operations, supplying a path parameter containing traversal sequences. Because no privileges are required, the attacker does not need a WordPress account. Deletion of files such as wp-config.php forces WordPress into the installation flow, which an attacker can hijack to connect the site to an attacker-controlled database and gain administrative control.
No verified public proof-of-concept code is available. Refer to the Patchstack advisory for additional technical context.
Detection Methods for CVE-2025-32633
Indicators of Compromise
- HTTP requests to wp-admin/admin-ajax.php or plugin endpoints containing ../ or URL-encoded %2e%2e%2f sequences in path parameters
- Unexpected deletion of WordPress core files such as wp-config.php, .htaccess, or index.php
- WordPress site unexpectedly displaying the installation setup screen at /wp-admin/install.php
- Web server logs showing 200 responses to plugin requests followed by file-not-found errors for previously valid resources
Detection Strategies
- Inspect web access logs for requests targeting Database Toolset plugin handlers with traversal patterns in query strings or POST bodies
- Enable file integrity monitoring on the WordPress installation directory to flag deletions of core and configuration files
- Correlate plugin request activity with subsequent filesystem changes using endpoint telemetry
Monitoring Recommendations
- Alert on any deletion event involving wp-config.php, .htaccess, or files under wp-content/plugins/ and wp-content/themes/
- Monitor for unauthenticated requests to plugin AJAX endpoints originating from a single source at high volume
- Track WordPress error logs for sudden database connection failures that indicate configuration file removal
How to Mitigate CVE-2025-32633
Immediate Actions Required
- Deactivate and remove the Database Toolset plugin if a patched version is not yet available
- Apply a web application firewall rule that blocks traversal sequences in requests to plugin endpoints
- Back up wp-config.php and other critical WordPress files to a location outside the web root
- Restrict write and delete permissions on the WordPress installation to the minimum required by the web server user
Patch Information
The vendor advisory hosted on Patchstack lists Database Toolset version 1.8.4 and earlier as affected. Administrators should consult the Patchstack advisory and update to the fixed release published by the maintainer when available. Until then, removal of the plugin is the most reliable mitigation.
Workarounds
- Block requests containing ../, ..\, or URL-encoded equivalents at the reverse proxy or WAF layer
- Disable the vulnerable plugin via WP-CLI using wp plugin deactivate database-toolset
- Use Patchstack or an equivalent virtual patching service to filter exploitation attempts against the plugin endpoint
# Deactivate the affected plugin until a patched version is installed
wp plugin deactivate database-toolset
wp plugin delete database-toolset
