CVE-2026-35621 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. OpenClaw before 2026.3.24 contains a privilege escalation vulnerability where the /allowlist command fails to re-validate gateway client scopes for internal callers, allowing operator.write-scoped clients to mutate channel authorization policy. Attackers can exploit chat.send to build an internal command-authorized context and persist channel allowFrom and groupAllowFrom policy changes reserved for operator.admin scope.. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
