At a glance

CVE-2026-4758 is a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the WP Job Portal WordPress plugin, affecting versions <= 2.4.9. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 2.5.0; sites on affected versions should update now. Disclosed March 2026, reported by daroo.

Vulnerability Overview

The 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 Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Reaching this weakness in WP Job Portal <= 2.4.9 takes an account at Subscriber level or above. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For WP Job Portal the fix is 2.5.0: builds <= 2.4.9 are affected, anything from 2.5.0 onward is not.

Remediation

Update to version 2.5.0, or a newer patched version

How does WordSec protect against this?

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Job Portal 2.5.0 closes this, and updating the plugin is the step that ends it.
