What is CVE-2026-41362?

OpenClaw versions prior to 2026.3.31 are susceptible to an improper cache isolation vulnerability within the Zalo webhook replay-dedupe mechanism. This flaw allows attackers, who have control over a single authenticated Zalo webhook path in multi-account contexts, to suppress genuine events across different accounts by manipulating the event_name and message_id parameters. As a result, critical events may not be processed, leading to potential miscommunication and operational issues in services relying on these webhooks.

Affected Version(s)

OpenClaw 2026.2.19 < 2026.3.31

OpenClaw 2026.3.31
