CVE-2026-22033

Estado: AnalizadaAlta (8.6)—

Label Studio is a multi-type data labeling and annotation tool. In 1.22.0 and earlier, a persistent stored cross-site scripting (XSS) vulnerability exists in the custom_hotkeys functionality of the application. An authenticated attacker (or one who can trick a user/administrator into updating their custom_hotkeys) can inject JavaScript code that executes in other users’ browsers when those users load any page using the templates/base.html template. Because the application exposes an API token endpoint (/api/current-user/token) to the browser and lacks robust CSRF protection on some API endpoints, the injected script may fetch the victim’s API token or call token reset endpoints — enabling full account takeover and unauthorized API access.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

Un atacante autenticado (o uno que pueda engañar a un usuario/administrador para que actualice sus custom_hotkeys) puede inyectar código JavaScript que se ejecuta en los navegadores de otros usuarios cuando esos usuarios cargan cualquier página utilizando la plantilla templates/base.html. Debido a que la aplicación expone un endpoint de token de API (/api/current-user/token) al navegador y carece de una protección CSRF robusta en algunos endpoints de API, el script inyectado puede obtener el token de API de la víctima o llamar a endpoints de restablecimiento de token — lo que permite la toma de control total de la cuenta y el acceso no autorizado a la API."
