What is CVE-2026-32053?

OpenClaw versions earlier than 2026.2.23 are susceptible to a vulnerability in the Twilio webhook event deduplication mechanism. The issue arises from the randomization of normalized event IDs upon each parse, which enables attackers to execute replay attacks. This could result in the triggering of duplicate events, leading to erroneous state transitions in call handling systems and overall corruption of call states. This flaw poses a significant risk to the reliability and integrity of integrations relying on Twilio webhooks.
