Vulnerability Title
Cronicle: Stored XSS in admin Activity Log via account full_name field
Source: CVE Program / CVE List V5
Vulnerability Description
Cronicle is a multi-server task scheduler and runner, with a web based front-end UI. Prior to 0.9.119, the administrator Activity Log in htdocs/js/pages/admin/Activity.js concatenates the attacker-controlled item.user.full_name value into HTML without applying encode_entities and inserts the result through this.div.html. The bundled pixl-server-user input filter can be bypassed by a tag containing a line break because its regular expression does not match newlines. An authenticated non-administrator can update the attacker's own name through /api/user/update using a valid session and current password; when free_accounts is enabled, an anonymous attacker can instead plant the name during self-registration. The stored name executes script in an administrator's session when the Activity Log is opened, enabling administrator takeover and subsequent command execution through privileged Cronicle features. This issue is fixed in version 0.9.119.
