CVE-2026-93354

Estado: AplazadaAlta (8.5)—

Taskview Community before 1.56.0 contains a missing authentication vulnerability that allows unauthenticated attackers to register arbitrary OAuth clients and take over user accounts by exploiting the OAuth 2.0 Dynamic Client Registration endpoint, which is enabled by default and requires no authentication. Attackers can send a POST request to the registration endpoint to obtain a client_id and client_secret, then craft a malicious authorization link pointing to an attacker-controlled redirect URI to capture authorization codes and exchange them for access tokens granting full API access to victim account data.

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.

CVE-2026-93354 requiere interacción del usuario (UI:A) para completar el flujo OAuth malicioso (T1203). El impacto principal es account takeover mediante registro no autenticado de clientes OAuth (T1098.001), con capacidad de manipulación de autenticación OAuth (T1556.006) y acceso a datos de cuenta

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.
