CVE-2026-62212 Details
Description
OpenClaw before 2026.5.28 contains a race condition in the MS Teams safeFetch DNS rebinding check. When the affected feature is enabled and reachable, a lower-trust caller or configured input path could win a timing window between the DNS validation check and use, allowing actions that should have required a stronger authorization or policy check. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path.
A race condition vulnerability has been identified in OpenClaw versions prior to 2026.5.28, specifically within the MS Teams safeFetch feature's DNS rebinding validation. When this feature is enabled and accessible, a lower-trust caller or input path could exploit the timing between the DNS check and its application, bypassing necessary authorization or policy requirements. The actual impact varies based on the operator's settings and the ability of lower-trust input to access the vulnerable path.
Users are advised to upgrade to OpenClaw version 2026.5.28 or later. Before upgrading, it is recommended to restrict the affected feature to trusted operators or disable it when not needed. As a general practice, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not required.
