CVE-2026-62210 Details
Description
OpenClaw versions before 2026.6.1 contain a denial of service vulnerability where remote media URLs can trigger slow-read attacks that exhaust gateway worker resources. Attackers with access to configured input paths can supply remote media URLs that consume gateway resources and reduce availability.
A denial-of-service vulnerability has been identified in OpenClaw versions prior to 2026.6.1. This vulnerability allows remote media URLs to trigger slow-read attacks that exhaust gateway worker resources. As a result, availability is reduced. Attackers with access to configured input paths can exploit this issue by supplying remote media URLs that consume gateway resources.
Users are advised to upgrade to OpenClaw version 2026.6.1 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.
