What is CVE-2026-41298?

The OpenClaw platform prior to version 2026.4.2 has a significant flaw where the POST /sessions/:sessionKey/kill endpoint does not enforce appropriate write scopes in identity-bearing HTTP modes. This oversight allows unauthorized users with read access to terminate active subagent sessions by exploiting this endpoint, undermining the integrity of session management and authorization controls.

Affected Version(s)

OpenClaw 0 < 2026.4.2
