Medium (5.3) in openclaw openclaw. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in openclaw 2026.3.28.
OpenClaw before 2026.3.28 contains a sender policy bypass vulnerability in the Google Chat and Zalouser extensions where route-level group allowlist policies silently downgrade to open policy. Attackers can exploit this policy resolution flaw to bypass sender restrictions and interact with bots despite configured allowlist restrictions.
