At a glance

CVE-2021-4364 is a medium-severity Improper Access Control vulnerability in the JobSearch WP Job Board WordPress plugin, affecting versions <= 1.8.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 1.8.2; sites on affected versions should update now. Disclosed October 2021, reported by Jerome Bruandet.

Vulnerability Overview

The JobSearch WP Job Board plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the jobsearch_add_job_import_schedule_call() function in versions up to, and including, 1.8.1. This makes it possible for authenticated attackers to add and/or modify schedule calls.

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.

CWE-284: Improper Access Control

JobSearch WP Job Board <= 1.8.1 carries this weakness at jobsearch_add_job_import_schedule_call(), and reaching it takes a caller who can reach the endpoint. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.

Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For JobSearch WP Job Board the fix is 1.8.2: builds <= 1.8.1 are affected, anything from 1.8.2 onward is not.

Remediation

Update to version 1.8.2, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: JobSearch WP Job Board 1.8.2 closes this, and updating the plugin is the step that ends it.
