Summary
OpenClaw < 2026.3.1 - Unbounded Memory Growth in Zalo Webhook via Query String Key Churn
Original description
The description as published by the source.
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.
