CVE-2026-62215 Details
Description
OpenClaw versions before 2026.6.5 contain an authentication bypass vulnerability in HTTP Canvas responses that allows lower-trust callers to forge trusted A2UI actions. Attackers can perform actions requiring stronger authorization by submitting crafted requests through configured input paths, bypassing intended policy checks.
An authentication bypass vulnerability has been identified in OpenClaw versions prior to 2026.6.5. This vulnerability allows lower-trust callers to forge trusted A2UI actions by exploiting HTTP Canvas responses. Attackers can bypass intended policy checks and perform actions that require stronger authorization by sending crafted requests through configured input paths.
Users are advised to upgrade to OpenClaw version 2026.6.5 or later. Before upgrading, it is recommended to restrict the affected feature to trusted operators or disable it when not needed. As a general hardening measure, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.
