At a glance
CVE-2024-2027 is a medium-severity Improper Input Validation vulnerability in the Real Media Library WordPress plugin, affecting versions <= 4.22.7. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 4.22.8; sites on affected versions should update now. Disclosed March 2024, reported by Ngô Thiên An (ancorn_).
Vulnerability Overview
The Real Media Library: Media Library Folder & File Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via its style attributes in all versions up to, and including, 4.22.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor access or above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
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-20: Improper Input Validation
Reaching this weakness in Real Media Library <= 4.22.7 takes an account at Contributor level or above. Improper input validation means the application accepts input without confirming it has the form, type or range the code downstream assumes.
The concrete impact depends on where the unvalidated value lands, which is why records in this class range from cosmetic bugs to full compromise. For Real Media Library the fix is 4.22.8: builds <= 4.22.7 are affected, anything from 4.22.8 onward is not.
Remediation
Update to version 4.22.8, or a newer patched version
How does WordSec protect against this?
An attacker needs Contributor 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: Real Media Library 4.22.8 closes this, and updating the plugin is the step that ends it.
