At a glance
CVE-2022-35726 is a medium-severity Missing Authorization vulnerability in the Video Gallery WordPress plugin, affecting versions <= 1.3.8. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.3.9; sites on affected versions should update now. Disclosed August 2022, reported by Muhammad Daffa.
Vulnerability Overview
The Video Gallery plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the deletecache function in versions up to, and including, 1.3.8. This makes it possible for unauthenticated attackers to clear the plugin's cache. The plugin added an "is_admin" check in version 1.3.5 but this would not be sufficient access control to prevent even unauthenticated attackers from exploiting the vulnerability.
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 privileges on the target site, and no interaction from a victim user.
CWE-862: Missing Authorization
Video Gallery <= 1.3.8 carries this weakness at is_admin, and reaching it 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 Video Gallery the fix is 1.3.9: builds <= 1.3.8 are affected, anything from 1.3.9 onward is not.
Remediation
Update to version 1.3.9, 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: Video Gallery 1.3.9 closes this, and updating the plugin is the step that ends it.
