CVE-2026-107353

Estado: Pendiente de análisisMedia (6.9)—

Las versiones de traverse (npm) desde la 0.3.6 hasta la 0.3.9, desde la 0.4.0 hasta la 0.4.6, desde la 0.5.0 hasta la 0.5.2 y desde la 0.6.0 hasta la 0.6.11 permiten la contaminación de prototipos (prototype pollution) a través de set(). Cuando la ruta pasada a set() atraviesa un valor primitivo, el siguiente segmento de la ruta se resuelve en el prototipo integrado de ese primitivo, por lo que una aplicación que pasa una ruta no confiable a set() permite a un atacante añadir o sobrescribir propiedades de String.prototype, Number.prototype o Boolean.prototype usando datos JSON simples, por ejemplo traverse({ name: 'bob' }).set(['name', '__proto__', 'polluted'], 'yes'). Object.prototype solo era alcanzable con un segmento de ruta que no fuera de datos, como un objeto cuyo toString devuelve un valor diferente en cada llamada, o a través de un Proxy que acepta una asignación sin almacenarla. Esto está corregido en 0.3.10, 0.4.7, 0.5.3 y 0.6.12.

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.

Librería npm expuesta públicamente vulnerable a prototype pollution (CWE-1321) vía parámetro untrusted path en set(), permitiendo manipulación de propiedades de prototipos integrados (String, Number, Boolean) y potencial ejecución de código malicioso.

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.

When the path passed to set() crosses a primitive value, the next path segment is resolved on that primitive's built-in prototype, so an application that passes an untrusted path to set() lets an attacker add or overwrite properties of String.prototype, Number.prototype, or Boolean.prototype using plain JSON data, for example traverse({ name: 'bob' }).set(['name', '__proto__', 'polluted'], 'yes'). Object.prototype was reachable only with a non-data path segment, such as an object whose toString returns a different value on each call, or through a Proxy that accepts an assignment without storing it. This is fixed in 0.3.10, 0.4.7, 0.5.3, and 0.6.12."
