CVE-2026-115513: OpenCATS stored cross-site scripting in MRU navigation panel

CVE-2026-115513 · Severity: high · CVSS 8.7 · Published 2026-10-22

OpenCATS is a web-based applicant tracking system that helps organizations manage job candidates and recruiting. The application fails to sanitize record names (candidates, companies, contacts, job orders, and lists) before storing and displaying them in the recent items navigation menu, allowing a low-privileged user to inject malicious JavaScript. An attacker can craft a payload that executes in the browsers of other users—including administrators—leading to session theft, cookie compromise, and administrative account takeover.

Technical details

The vulnerability is a stored XSS flaw in lib/MRU.php's getFormatted() function, which renders unsanitized record names without HTML escaping in the navigation panel displayed across nearly all pages. An authenticated user with low privileges can inject arbitrary HTML/JavaScript by setting a record name field; the payload persists and executes whenever any other user views the MRU panel, including Site Administrators. The attacker gains code execution in the victim's session context, enabling privilege escalation.
