CVE-2026-9104 is a stored cross-site scripting vulnerability in the Draft List WordPress plugin (up to version 2.6.3). The flaw arises from improper neutralization of input during web page generation, specifically in draft post titles. Authenticated users with author-level access can inject arbitrary web scripts that execute in the context of users viewing the injected pages, including unauthenticated users and subscribers lacking edit capabilities. The vulnerability is due to insufficient input sanitization and output escaping, allowing attribute-breakout payloads to execute. No official patch or remediation level has been published, and no known exploits are reported in the wild.

Successful exploitation allows an authenticated author-level user to inject malicious scripts into draft post titles that execute in the browsers of other users, including unauthenticated visitors and subscribers. This can lead to information disclosure or session hijacking limited to the affected site context. The vulnerability does not impact availability and requires author-level privileges to inject payloads. The CVSS score of 6.4 reflects a medium severity with network attack vector, low attack complexity, and no user interaction required.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict author-level access to trusted users only and consider disabling or limiting use of the Draft List plugin. Monitor for plugin updates from the vendor that address this vulnerability. Avoid relying on generic mitigations as the vulnerability specifically involves insufficient input sanitization and output escaping in draft post titles.
