Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.4.2

Description An improper access control issue exists in the iOS A2UI bridge, which incorrectly treats generic local-network pages as trusted origins. This allows attackers to inject unauthorized agent.request runs by loading attacker-controlled pages from tailnet hosts or the local network, leading to session state pollution and budget consumption.
