At a glance
CVE-2026-12241 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Advanced Woo Labels WordPress plugin, affecting versions <= 2.51. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 2.52; sites on affected versions should update now. Disclosed September 2026, reported by Osvaldo Noe Gonzalez Del Rio (Os).
Vulnerability Overview
The Advanced Woo Labels – Product Labels & Badges for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to an improperly secure capability check on the 'save_meta_boxes' function in all versions up to, and including, 2.51. This makes it possible for authenticated attackers, with Contributor-level access and above, to create AWS labels that are rendered without proper escaping. The vulnerability was partially patched in version 2.46.
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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Advanced Woo Labels <= 2.51 carries this weakness at save_meta_boxes, and reaching it takes an account at Subscriber level or above. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Advanced Woo Labels the fix is 2.52: builds <= 2.51 are affected, anything from 2.52 onward is not.
Remediation
Update to version 2.52, or a newer patched version
How does WordSec protect against this?
An attacker needs Subscriber 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: Advanced Woo Labels 2.52 closes this, and updating the plugin is the step that ends it.
