Aliases CVE-2026-32066
Summary OpenClaw has unbounded memory growth in Zalo webhook via query-string key churn (unauthenticated DoS) ### 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`
