📦openclaw

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.

Description

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.
