Status: DeferredCritical (9.4)—

Use of Insufficiently Random Values vulnerability in form-data allows HTTP Parameter Pollution (HPP). This vulnerability is associated with program files lib/form_data.Js.

This issue affects form-data: < 2.5.4, 3.0.0 - 3.0.3, 4.0.0 - 4.0.3.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vulnerabilidad de valores aleatorios insuficientes (CWE-330) en librería form-data permite HTTP Parameter Pollution desde red sin autenticación (AV:N/PR:N). Impacta integridad de datos (VI:H) mediante manipulación de parámetros HTTP.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
