At a glance
CVE-2026-119178 is a medium-severity Improper Neutralization of Input During Web Page Generation vulnerability in the Smart Cookie Kit WordPress plugin, affecting versions <= 2.3.2. It carries a CVSS score of 5.4 (reachable over the network). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed November 2026, reported by Santh.
Vulnerability Overview
The Smart Cookie Kit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 2.3.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is specifically crafted to survive wp_kses on save by storing hostile characters inside allowed HTML elements, with the attribute-breaking double-quote smuggled inside a permitted <code> body and reconstructed into a <abbr title> attribute only at render time by the plugin's own output buffer; exploitation requires an administrator to approve the comment and subsequently view the affected public post.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user.
CWE-79: Improper Neutralization of Input During Web Page Generation
Smart Cookie Kit <= 2.3.2 carries this weakness at comment, and reaching it takes no account at all. 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. No fixed build of this plugin is recorded for Smart Cookie Kit yet, so installs running <= 2.3.2 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
