CVE-2026-9104
At a glance
CVE-2026-9104 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Draft List WordPress plugin, affecting versions 2.6.3. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 2.6.4; sites on affected versions should update now. Disclosed May 2026, reported by Athiwat Tiprasaharn (Jitlada).
Vulnerability Overview
The Draft List plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Draft Post Title in all versions up to, and including, 2.6.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The unescaped injection path is triggered specifically when the viewing user lacks edit capabilities, meaning payloads embedded in draft post titles via attribute-breakout techniques execute for unauthenticated users and subscribers.
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')
Reaching this weakness in Draft List 2.6.3 takes an account at Author 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 Draft List the fix is 2.6.4: builds 2.6.3 are affected, anything from 2.6.4 onward is not.
Remediation
Update to version 2.6.4, or a newer patched version
How does WordSec protect against this?
An attacker needs Author 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: Draft List 2.6.4 closes this, and updating the plugin is the step that ends it.
