OpenClaw: Zalo webhook rate limiting could be bypassed before secret validation

發布日:2026/3/13修改日:2026/4/6

描述

### Summary The Zalo webhook handler applied request rate limiting only after webhook authentication succeeded. Requests with an invalid secret returned `401` but did not count against the rate limiter, allowing repeated secret guesses without triggering `429`. ### Impact This made brute-force guessing materially easier for weak but policy-compliant webhook secrets. Once the secret was guessed, an attacker could submit forged Zalo webhook traffic. ### Affected versions `openclaw` `<= 2026.3.11` ### Patch Fixed in `openclaw` `2026.3.12`. Rate limiting now applies before successful authentication is required, closing the pre-auth brute-force gap. Users should update to `2026.3.12` or later and prefer strong webhook secrets.
