CVE-2026-35670
OpenClaw before 2026.3.22 contains a webhook reply delivery vulnerability that allows attackers to rebind chat replies to unintended users by exploiting mutable username matching instead of stable numeric user identifiers. Attackers can manipulate username changes to redirect webhook-triggered replies to different users, bypassing the intended recipient binding recorded in webhook events.
