Craft CMS is a content management system (CMS). In versions 5.0.0-RC1 through 5.9.22, an author-level control panel user can store a malicious JavaScript payload in an entry title. When an admin, or any control panel user with saveEntries for the same Structure section, drags another entry under the poisoned entry in table view, the payload executes in the victim’s session. The issue is exploitable because the title is escaped into data-title by the server, decoded again by the browser, read with jQuery .data('title'), and then concatenated into a new HTML string without attribute escaping. To exploit, an attacker must have an existing control panel account (Author role minimum), the victim must perform a drag operation (not just visit the page), and the victim’s session needs to be elevated at trigger time. This issue has been fixed in version 5.9.23.

Affected: Packagist: craftcms/cms

# Stored XSS via Structure entry title in table view

## Summary

An Author-level control panel user can store a JavaScript payload in an entry title. When an admin, or any control panel user with `saveEntries` for the same Structure section, drags another entry under the poisoned entry in table view, the payload executes in the victim’s session.

The issue is exploitable because the title is escaped into `data-title` by the server, decoded again by the browser, read with jQuery `.data('title')`, and then concatenated into a new HTML string without attribute escaping.

Execution was verified with `alert(document.domain)`. Impact was verified against an elevated admin session by changing the admin user’s email through `users/save-user`, then using the password-reset flow to take over the account.

## Preconditions

- Attacker has `createEntries` + `saveEntries` on a Structure-type section (Author-style CP account; no admin permission required). - Victim has `saveEntries` on the same section. Craft only renders drag handles when `structureEditable` is true, which requires this permission, so any admin qualifies. - Section must be type Structure. Channel and Single sections are unaffected. - Poisoned entry must have no children at the time of the drag (fires on the 0-to-1 descendant transition). - For the email-change account-takeover path, the victim must currently have an elevated session. The stored XSS itself does not require elevation.
