CVE-2025-30966 Overview
CVE-2025-30966 is a path traversal vulnerability [CWE-35] affecting the WPJobBoard plugin for WordPress. The flaw allows an authenticated attacker with low privileges to traverse directories outside the intended file scope. Successful exploitation can expose sensitive files and modify limited data within the WordPress installation. The vulnerability affects WPJobBoard versions up to and including 5.11.1, as documented in the Patchstack WP Job Board Vulnerability advisory.
Critical Impact
Authenticated attackers can traverse the file system, read sensitive configuration files, and alter files reachable by the WordPress process.
Affected Products
- NotFound WPJobBoard plugin for WordPress
- WPJobBoard versions through 5.11.1
- WordPress installations that expose the plugin's file-handling endpoints

Technical Details for CVE-2025-30966
Vulnerability Analysis
The vulnerability is a path traversal weakness classified under [CWE-35] (Path Traversal: .../...//). WPJobBoard fails to properly neutralize traversal sequences in a file path parameter processed by the plugin. An attacker who supplies crafted input with directory traversal characters can escape the intended base directory. The result is unauthorized access to files elsewhere on the file system that the WordPress process can read or modify.
The attack requires network access and low-privilege authentication. No user interaction is needed to trigger the flaw. Impact is limited to partial confidentiality and integrity loss, with no availability effect. See the Patchstack advisory for the vendor-tracked technical summary.
Root Cause
The root cause is insufficient sanitization of user-supplied path input within the WPJobBoard plugin. The affected code accepts a filename or path parameter and concatenates it into a filesystem operation without normalizing traversal sequences such as ../ or encoded variants. Because the plugin does not enforce a canonical base directory check, requests can resolve to arbitrary locations reachable by the PHP process.
Attack Vector
Exploitation requires an authenticated session with at least contributor-level or subscriber-level privileges, depending on the exposed endpoint. The attacker sends a crafted HTTP request containing traversal sequences in a path parameter handled by WPJobBoard. The plugin resolves the path and reads or writes the targeted file, returning contents or persisting attacker-influenced data. No verified public proof-of-concept is available at the time of publication.

Detection Methods for CVE-2025-30966
Indicators of Compromise
- HTTP requests to WPJobBoard endpoints containing ../, ..\, or URL-encoded traversal sequences such as %2e%2e%2f
- Unexpected reads of wp-config.php, .htaccess, or files outside the plugin's directory by the web server user
- Anomalous file access patterns from PHP processes tied to WPJobBoard handlers
Detection Strategies
- Inspect WordPress and web server access logs for request parameters containing traversal patterns targeting WPJobBoard paths
- Deploy Web Application Firewall (WAF) rules that block traversal sequences in query and POST parameters
- Correlate authenticated session activity with sensitive file access events on the WordPress host
Monitoring Recommendations
- Enable file integrity monitoring on wp-config.php, .htaccess, and plugin directories
- Alert on PHP processes reading files outside the WordPress webroot or plugin scope
- Track authenticated user activity for repeated requests to WPJobBoard endpoints with path parameters
How to Mitigate CVE-2025-30966
Immediate Actions Required
- Identify all WordPress instances running WPJobBoard versions through 5.11.1 and prioritize patching
- Restrict low-privilege account creation on affected WordPress sites until the plugin is updated
- Apply WAF rules to block path traversal patterns targeting plugin endpoints
- Review web server and PHP-FPM permissions to limit filesystem reach of the WordPress process
Patch Information
Refer to the Patchstack WP Job Board Vulnerability advisory for the current fixed version and vendor guidance. Update WPJobBoard to the latest release published by the vendor.
Workarounds
- Temporarily disable the WPJobBoard plugin if a patched version is not yet deployed
- Enforce least-privilege on WordPress user roles and remove unnecessary accounts
- Configure the web server to deny direct access to sensitive files including wp-config.php and .env
- Deploy a WAF signature that blocks ../ and encoded traversal variants in requests to WPJobBoard endpoints
