Vulnerability details
The vulnerability allows a remote user to recover a Gateway password and potentially gain shared-secret operator authority.
The vulnerability exists due to exposure of deterministic hashes of unredacted configuration data in OpenClaw configuration responses when returning redacted configuration. A remote user can obtain these hashes and test password candidates offline, bypassing the rate-limited Gateway authentication path, to recover the Gateway password and potentially gain shared-secret operator authority.
Practical exploitation requires a weak password and sufficient knowledge of every other hashed configuration value. Secret references are not affected in the same way.
