At a glance
CVE-2023-41866 is a medium-severity Missing Authorization vulnerability in the Automatic YouTube Gallery WordPress plugin, affecting versions <= 2.3.3. 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 2.3.5; sites on affected versions should update now. Disclosed September 2023, reported by Rafshanzani Suhada.
Vulnerability Overview
The Automatic YouTube Gallery plugin for WordPress is vulnerable to unauthorized plugin settings change due to a missing capability check on the ajax_callback_save_api_key and ajax_callback_delete_cache functions in versions up to, and including, 2.3.3. This makes it possible for authenticated attackers, with subscriber-level access and above, to update the plugin API key and delete the plugin cache.
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-862: Missing Authorization
Reaching this weakness in Automatic YouTube Gallery <= 2.3.3 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Automatic YouTube Gallery the fix is 2.3.5: builds <= 2.3.3 are affected, anything from 2.3.5 onward is not.
Remediation
Update to version 2.3.5, 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: Automatic YouTube Gallery 2.3.5 closes this, and updating the plugin is the step that ends it.
