At a glance
CVE-2026-10092 is a high-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Cincopa video and media plug-in WordPress plugin, affecting versions <= 1.163. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.164; sites on affected versions should update now. Disclosed June 2026, reported by theviper17y.
Vulnerability Overview
The Cincopa video and media plug-in plugin for WordPress is vulnerable to Stored Cross-Site Scripting via cincopa Shortcode in Post Comments in all versions up to, and including, 1.163 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. Exploitation is possible because the plugin processes the [cincopa] shortcode via a comment_text filter hook, allowing unauthenticated visitors who can post comments to supply a malicious shortcode argument that persists in the database.
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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Cincopa video and media plug-in <= 1.163 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. For Cincopa video and media plug-in the fix is 1.164: builds <= 1.163 are affected, anything from 1.164 onward is not.
Remediation
Update to version 1.164, or a newer patched version
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. None of that substitutes for the fix: Cincopa video and media plug-in 1.164 closes this, and updating the plugin is the step that ends it.
