CVE-2026-28476

Estado: AnalizadaMedia (6.3)—

OpenClaw versions prior to 2026.2.14 contain a server-side request forgery vulnerability in the optional Tlon Urbit extension that accepts user-provided base URLs for authentication without proper validation. Attackers who can influence the configured Urbit URL can induce the gateway to make HTTP requests to arbitrary hosts including internal addresses.

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).
