OpenClaw before 2026.3.28 contains a privilege escalation vulnerability in the chat.send endpoint that allows write-scoped gateway callers to persist admin-only verboseLevel session overrides. Attackers can exploit the /verbose parameter to bypass access controls and expose sensitive reasoning or tool output intended to be restricted to administrators.

Ein Angreifer kann mehrere Schwachstellen in OpenClaw ausnutzen, um erweiterte Rechte zu erlangen, beliebigen Code auszuführen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, vertrauliche Informationen offenzulegen, einen Denial-of-Service-Zustand herbeizuführen oder andere, nicht näher spezifizierte Angriffe durchzuführen.
- GHSA-5h2w-qmfp-ggp6OpenClaw: Gateway `operator.write` can reach admin-only persisted `verboseLevel` via `chat.send` `/verbose`2026-03-31ghsa · osvUS
## Summary The `chat.send` path let authorized write-scoped callers persist `/verbose` session overrides even though the same stored session mutation is admin-only through `sessions.patch`. ## Impact A write-scoped gateway caller could persist verbose output for later runs and expose more reasoning or tool output than the operator intended. ## Affected Component `src/auto-reply/reply/directive-handling.impl.ts, src/gateway/sessions-patch.ts` ## Fixed Versions - Affected: `<= 2026.3.24` - Patched: `>= 2026.3.28` - Latest stable `2026.3.28` contains the fix. ## Fix Fixed by commit `c603123528` (`fix(gateway): require admin for persisted verbose defaults`).
