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.
