CVSS 7.7 · HIGH

CVE-2026-43576

OpenClaw before 2026.4.5 contains a server-side request forgery vulnerability in the CDP /json/version WebSocket endpoint that allows attackers to pivot to untrusted second-hop targets. The webSocketDebuggerUrl response field is not properly validated, enabling attackers to redirect connections to arbitrary hosts and perform SSRF-style attacks.

Analysis

OpenClaw is a niche software project, likely an open-source game engine reimplementation, which is not part of the standard web or mobile development stack. While the SSRF vulnerability in the WebSocket endpoint is high severity, the software lacks the widespread deployment necessary to impact the general MexicoDev community.

How to read this card

Actively exploited

KEV (Known Exploited Vulnerabilities) is CISA's catalog of CVEs confirmed as actively exploited in the real world. If a CVE is on KEV, someone is already using it in attacks.

CVSS 10.0

CVSS 10.0 — máxima severidad teórica. Explotable de forma remota, sin privilegios, con impacto total. Aún no confirmada como explotada en el mundo real, pero parchea ya.
