Official Description
OpenClaw before 2026.4.2 contains an improper access control vulnerability in the iOS A2UI bridge that treats generic local-network pages as trusted origins. Attackers can inject unauthorized agent.request runs by loading attacker-controlled pages from local-network or tailnet hosts, polluting session state and consuming budget.
Technical Analysis
CVE-2026-41398 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
