At a glance

CVE-2023-4924 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the BEAR WordPress plugin, affecting versions <= 1.1.3.3. It carries a CVSS score of 5.4 (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 1.1.4; sites on affected versions should update now. Disclosed September 2023, reported by Marco Wotschka.

Vulnerability Overview

The BEAR for WordPress is vulnerable to Missing Authorization in versions up to, and including, 1.1.3.3. This is due to missing capability checks on the woobe_bulkoperations_delete function. This makes it possible for authenticated attackers, with subscriber access or higher, to delete products.

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-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in BEAR <= 1.1.3.3 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For BEAR the fix is 1.1.4: builds <= 1.1.3.3 are affected, anything from 1.1.4 onward is not.

Remediation

Update to version 1.1.4, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to BEAR: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: BEAR 1.1.4 closes this, and updating the plugin is the step that ends it.
