Does this matter?

Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.

Description

OpenClaw versions before 2026.8.1 contain an authorization bypass vulnerability in the sessions.create endpoint that allows operator.write callers to modify session configurations reserved for operator.admin scope. Attackers with write-scoped credentials can change existing session model, provider, thinking level, and auth-profile settings to redirect traffic and bypass administrative access controls.
