CVE-2026-22794

Estado: AnalizadaAlta (8.8)—

Appsmith is a platform to build admin panels, internal tools, and dashboards. Prior to 1.93, the server uses the Origin value from the request headers as the email link baseUrl without validation. If an attacker controls the Origin, password reset / email verification links in emails can be generated pointing to the attacker’s domain, causing authentication tokens to be exposed and potentially leading to account takeover. This vulnerability is fixed in 1.93.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

UI:R (requiere interacción del usuario para hacer clic en enlace malicioso); impactos: tokens de autenticación expuestos (T1078.001) y potencial takeover de cuenta (T1556.001 por manipulación de credenciales de acceso).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
