CVE-2026-77074

Estado: AnalizadaMedia (6)—

n8n versions before 1.123.69 contain a server-side request forgery vulnerability in the Edit Image node's Draw Text operation that allows authenticated users to inject MVG primitives. Attackers can craft malicious text values to issue blind outbound HTTP requests to arbitrary addresses or access local files.

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).
