CVE-2026-82536

Estado: AplazadaAlta (7.7)—

Roo-Code through 3.54.0 contains an auto-approve bypass vulnerability in the shell command parsing logic that allows attackers to execute denied shell commands by exploiting the omission of the bash pipe operator from the command parser's operator token set. Attackers can craft a command line with an allowlisted prefix followed by the stderr-redirecting pipe operator and a denied command, causing the parser to approve the full pipeline while bash executes the denied component with the agent's auto-execute privileges on the developer's machine.

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.

Requiere interacción del usuario (UI:P) para abrir/usar Roo-Code. Ejecuta comandos shell denied mediante bypass del parser (T1059). Potencial acceso a credenciales del desarrollador en la máquina (T1078).

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.
