EPSS · scored 2026-10-27

OpenClaw versions prior to 2026.2.23 contain an allowlist bypass vulnerability in system.run guardrails that allows authenticated operators to execute unintended commands. When /usr/bin/env is allowlisted, attackers can use env -S to bypass policy analysis and execute shell wrapper payloads at runtime.

  • WID-SEC-W-2026-0586OpenClaw: Mehrere SchwachstellenDeutsch2026-03-03csaf · cert_bundDE

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

    ### Summary In `allowlist` mode, `system.run` guardrails could be bypassed through `env -S`, causing policy-analysis/runtime-execution mismatch for shell wrapper payloads. ### Severity Rationale (Medium) This issue is rated **medium** because it is a guardrail/policy bypass in OpenClaw's trusted-operator model, not an authentication boundary break. - Authenticated Gateway callers are trusted operators by design. - `exec` approvals/allowlists are operator safety controls. - The bug still weakens expected safety behavior and can enable unintended command execution when untrusted content influences tool input. ### Affected Packages / Versions - Package: `openclaw` (npm) - Vulnerable versions: `<= 2026.2.22-2` - Patched versions: `>= 2026.2.23` Latest published npm version checked during triage: `2026.2.22-2`. ### Technical Impact When `/usr/bin/env` is allowlisted, `env -S 'sh -c ...'` could be treated as allowed non-wrapper argv while runtime still executes shell-wrapper semantics. ### Fix Commit(s) - `a1c4bf07c6baad3ef87a0e710fe9aef127b1f606` (core allowlist/runtime parity hardening) - `3f923e831364d83d0f23499ee49961de334cf58b` (explicit `env -S` regressions) ### Release Process Note `patched_versions` is pre-set to `>= 2026.2.23`, so this advisory is now public. OpenClaw thanks @tdjackey for reporting.
