CVE-2026-42430Network attack vector

Private-target access via unchecked Playwright navigation

Published Apr 28, 2026 · Updated Apr 28, 2026

SSRF in OpenClaw before 2026.4.8 allows remote authenticated users to reach private targets through Playwright request-time navigation. The strict browser SSRF guard validates direct destinations but misses request-time navigation that sends Playwright to a private address. Exploitation requires low-privileged access and passive user interaction, and the bounded consequence is access to restricted private-network resources.
