CVE-2026-4758
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 WP Job Portal plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'WPJOBPORTALcustomfields::removeFileCustom' function in all versions up to, and including, 2.4.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
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 WP Job Portal WordPress plugin up to version 2.4.9 contains an arbitrary file deletion vulnerability in the WPJOBPORTALcustomfields::removeFileCustom function. Due to insufficient file path validation, any authenticated user with Subscriber-level access can supply a crafted file path (including path traversal sequences or absolute paths) to delete arbitrary files on the server filesystem. Deletion of sensitive files like wp-config.php enables full site compromise and remote code execution.

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 WP Job Portal plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'WP Job Portal' in the listAffected if The WP Job Portal plugin is active and installed with version 2.4.9 or earlier
-
Check installed plugin versionClick on the WP Job Portal plugin in the Plugins list to view the version number, or inspect the plugin header in /wp-content/plugins/wp-job-portal/ folderAffected if Version is 2.4.9 or lower (any version up to and including 2.4.9 is affected)
-
Confirm user registration is enabledGo to WordPress Settings > General > Membership and check 'Anyone can register' is selected, or query the 'users_can_register' option in wp_options tableAffected if User registration is enabled, allowing potential attackers to create subscriber accounts
-
Check for subscriber-level user accountsGo to Users > All Users in WordPress admin and look for users with 'Subscriber' role, or query wp_users and wp_usermeta for user_level 0 or subscriber roleAffected if Any subscriber-level user accounts exist in the system
-
Verify the removeFileCustom function is accessibleInspect the file /wp-content/plugins/wp-job-portal/includes/classes/customfields.php (or similar path) for the removeFileCustom function and confirm it lacks proper path validation using realpath() or similar checksAffected if The function exists and does not validate that the file path is within an allowed directory before deletion
A user is affected if WP Job Portal version 2.4.9 or earlier is installed AND user registration is enabled or subscriber accounts exist, allowing authenticated users to delete arbitrary files via the removeFileCustom function.

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 the WP Job Portal plugin to the latest patched version. If no patch is available, implement strict whitelist-based path validation in the removeFileCustom function to ensure only files within allowed upload directories can be deleted, and disable the function for low-privilege users until patched.
2.5.0 or later (check WordPress plugin repository for latest patched version)
- 1. Backup your WordPress site and database before making any changes.
- 2. Navigate to Plugins > Installed Plugins in the WordPress admin dashboard.
- 3. Locate the WP Job Portal plugin in the list.
- 4. Check the current installed version (if it's 2.4.9 or lower, the site is vulnerable).
- 5. If an update is available, click 'Update Now' to install the latest version that contains the security fix.
- 6. After updating, verify the new version number matches the patched release.
- 7. Test that the WP Job Portal functionality works correctly after the update.
- 8. If automatic updates are not enabled, consider enabling them for this plugin or manually checking for updates regularly.
