CVE-2026-53846
OpenClaw before 2026.4.29 contains a path traversal vulnerability in the install helper that allows workspace .env files to override the npm_execpath configuration used for bundled runtime dependency installation. Attackers with workspace access can execute unintended local package-manager executables during dependency setup to compromise the build environment.
CVSS
- Versión: 4.0
- Vector: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X
- Puntuación base: 7
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.17%
- Percentil entre todas las CVEs puntuadas: 6
- Fecha de la puntuación: 4/10/2026
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.
- Explotación
T1203Exploitation for Client Executionexecution85 % - Impacto principal
T1574.007Path Interception by PATH Environment Variablestealth · execution80 % - Impacto secundario
T1059Command and Scripting Interpreterexecution75 %
Vector CVSS con AV:L, UI:A y AT:P indica explotación local con interacción del usuario (abrir/procesar un archivo preparado en el workspace). Path traversal en .env permite secuestro de DLL (T1574.007) en cadena de dependencias npm, logrando ejecución de código arbitrario.
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.
