CVE-2026-41343
low-risk
Published 2026-04-23
OpenClaw before 2026.3.31 lacks a shared pre-auth concurrency budget on the public LINE webhook path, allowing attackers to cause transient availability loss. Remote attackers can flood the webhook endpoint with concurrent requests before signature verification to exhaust resources and degrade service availability.
