OpenClaw < 2026.4.4 - Rate-Limit Bypass via Concurrent Async Authentication Attempts

Title source: cna

Description

OpenClaw before 2026.4.4 contains a race condition vulnerability in shared-secret authentication that allows concurrent asynchronous requests to bypass the per-key rate-limit budget. Attackers can exploit this by sending multiple simultaneous authentication attempts to circumvent intended rate-limiting protections on Tailscale-capable paths.
