CVE-2026-32066

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

### Summary Unauthenticated requests to a reachable Zalo webhook endpoint could trigger unbounded in-memory key growth by varying query strings on the same valid webhook route. ### Impact An attacker could cause memory pressure and potential process instability or OOM, degrading availability. ### Fix Webhook security tracking now normalizes keys to matched webhook path semantics (query excluded) and bounds/prunes tracking state to prevent unbounded growth. ### Affected and Patched Versions - Affected: `<= 2026.2.26` - Patched: `2026.3.1`

OpenClaw versions prior to 2026.3.1 contain an unbounded memory growth vulnerability in the Zalo webhook endpoint that allows unauthenticated attackers to trigger in-memory key accumulation by varying query strings. Remote attackers can exploit this by sending repeated requests with different query parameters to cause memory pressure, process instability, or out-of-memory conditions that degrade service availability.
