CVE-2026-63093

Estado: AnalizadaAlta (8.7)—

Cursor for Windows version 3.2.16 contains a binary planting vulnerability that allows remote attackers to achieve arbitrary code execution by placing a malicious git.exe file in the repository root directory. When a developer clones and opens a crafted repository, Cursor automatically resolves and executes the workspace-resident git.exe during IDE startup and on a recurring timed cadence without any user interaction, running the malicious binary under the privileges of the current user.

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 + interacción con archivo preparado (repositorio malicioso) → T1203. DLL hijacking via git.exe en raíz → T1574.007. Ejecución arbitraria de código como impacto secundario.

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.
