CVE-2026-32031Public exploitNetwork attack vector

Unauthenticated plugin API access via path mismatch

Published Mar 19, 2026 · Updated Mar 19, 2026

Authentication bypass in OpenClaw before 2026.2.26 allows remote attackers to access protected plugin channel APIs over HTTP. The server-http guard checks only exact raw /api/channels paths, while plugin handlers can decode or lowercase alternate encodings before routing them. A reachable Gateway with a canonicalizing plugin route is required, and the bypass permits unauthorized access and actions exposed by that plugin API.
