Affected: OpenClaw

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.

 https://vulnerability.circl.lu/vuln/ghsa-wr6m-jg37-68xh GHSA-wr6m-jg37-68xh — OpenClaw has unbounded memory growth in Zalo webhook via query-string key churn (unauthenticated DoS) 2026-09-28T12:47:24.892916+00:00

Affected: npm: openclaw

### 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`
