CVE-2026-59196

Estado: AnalizadaAlta (7.1)—

pnpm is a package manager. Prior to 10.34.4 and 11.7.0, a crafted lockfile alias could be joined directly under a hoisted node_modules directory. Traversal aliases could escape that directory, while reserved aliases such as .bin or .pnpm could overwrite pnpm-owned layout. This vulnerability is fixed in 10.34.4 and 11.7.0.

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 + AV:N indica explotación en cliente (lockfile preparado). Impacto: sobrescritura de directorios pnpm (T1565.001) y potencial escalada vía .bin (T1068).

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.
