CVE-2026-35617Network attack vector

Authorization bypass via mutable group-name policy lookup

Published Apr 9, 2026 · Updated Apr 9, 2026

Authorization bypass in OpenClaw before 2026.3.25 allows remote authenticated users to access protected Google Chat resources. The Google Chat inbound access policy matches configured groups by mutable space display names instead of stable space IDs, allowing renamed or colliding spaces to inherit another group's policy. Exploitation requires Google Chat space access and the ability to change or collide its display name, exposing policy-protected commands, prompts, or resources without host-level control.
