AI-suggested

A fix is available in OpenClaw version 2026.3.25 and later, which corrects the order of operations to validate webhook signatures before parsing JSON bodies. Users should upgrade to version 2026.3.25 or later to remediate this vulnerability. No other mitigation or workaround is indicated.

Description

OpenClaw versions before 2026.3.25 have a vulnerability where JSON request bodies are parsed before webhook signatures are validated. This allows unauthenticated remote attackers to send malicious webhook requests that trigger resource-intensive JSON parsing, potentially causing a denial of service by exhausting server resources.
