EPSS · scored 2026-10-27

OpenClaw versions prior to 2026.2.2 contain an authorization bypass vulnerability where clients with operator.write scope can approve or deny exec approval requests by sending the /approve chat command. The /approve command path invokes exec.approval.resolve through an internal privileged gateway client, bypassing the operator.approvals permission check that protects direct RPC calls.

  • WID-SEC-W-2026-0424OpenClaw: Mehrere SchwachstellenDeutsch2026-02-15csaf · cert_bundDE

    Ein Angreifer kann diese Schwachstellen in OpenClaw ausnutzen, um beliebigen Programmcode auszuführen, sich erhöhte Berechtigungen zu verschaffen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, einen Denial-of-Service-Zustand herbeizuführen, vertrauliche Informationen offenzulegen oder andere, nicht näher bezeichnete Angriffe durchzuführen.

  • GHSA-mqpw-46fh-299hOpenClaw authorization bypass: operator.write can resolve exec approvals via chat.send -> /approve2026-02-17ghsa · osvUS

    ## Summary ### What this means (plain language) If you give a client “chat/write” access to the gateway (`operator.write`) but you do not intend to let that client approve exec requests (`operator.approvals`), affected versions could still let that client approve/deny a pending exec approval by sending the `/approve` chat command. This is mainly relevant for shared or multi-client setups where different tokens are intentionally scoped differently. Single-operator installs are typically less impacted. ### Technical summary A gateway client authenticated with a device token scoped only to `operator.write` (without `operator.approvals`) could approve/deny pending exec approval requests by sending a chat message containing the built-in `/approve` command. `exec.approval.resolve` is correctly scoped to `operator.approvals` for direct RPC calls, but the `/approve` command path invoked it via an internal privileged gateway client. ## Affected Packages / Versions - `openclaw` (npm): `< 2026.2.2` ## Fix - Fixed in `openclaw` `2026.2.2`. - Fix commit(s): `efe2a464afcff55bb5a95b959e6bd9ec0fef086e`. - Change: when `/approve` is invoked from gateway clients (webchat/internal channel), it now requires the requesting client to have `operator.approvals` (or `operator.admin`). ## Workarounds - Upgrade to `openclaw >= 2026.2.2`. - If you cannot upgrade: avoid issuing write-only device tokens to untrusted clients; disable text commands (`commands.text=false`) or restrict access to the webchat/control UI. ## References - Fix: `src/auto-reply/reply/commands-approve.ts` - Coverage: `src/auto-reply/reply/commands-approve.test.ts` ## Release Process Note This advisory is kept in draft; once the fixed npm versions are available, it can be published without further edits. Thanks @yueyueL for reporting.
