Executive Summary

This vulnerability exists in OpenClaw versions before 2026.3.1 and involves the Zalo webhook endpoint. It allows unauthenticated attackers to cause unbounded memory growth by sending repeated requests with varying query strings to the same webhook route.

The repeated requests cause the system to accumulate keys in memory without limits, leading to memory exhaustion.

Impact Analysis

The impact of this vulnerability is primarily related to availability and stability. Attackers can cause memory pressure on the affected system, which may lead to process instability or out-of-memory conditions.

This can result in denial of service as the system may crash or become unresponsive due to exhausted memory resources.
