No affected components available
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.
