OpenClaw (npm package openclaw) versions before 2026.8.1 could leak deterministic hashes derived from the original, unredacted configuration in redacted configuration responses. These hashes could be used as offline password verifiers if the Gateway password had low entropy and other configuration values were reconstructable. This vulnerability allows an attacker with access to the redacted configuration to test password guesses offline, bypassing rate-limiting on Gateway authentication. The issue does not affect secret references and is fixed in version 2026.8.1.
AI Analysis
Technical Summary
The OpenClaw npm package prior to version 2026.8.1 included deterministic hashes computed over the original, unredacted configuration within redacted configuration responses. When the Gateway password was weak and the rest of the configuration could be reconstructed, these hashes functioned as offline password verifiers. An attacker able to retrieve the redacted configuration (e.g., via config.get) could perform offline password guessing without triggering rate limits on the Gateway authentication mechanism. Successful password recovery could grant shared-secret operator authority. Secret references were not impacted. The vulnerability is resolved in version 2026.8.1.
Potential Impact
An attacker with access to the redacted configuration can perform offline password guessing attacks against the Gateway password if it has low entropy, bypassing rate-limiting protections. This could lead to unauthorized access with shared-secret operator privileges, potentially compromising confidentiality, integrity, and availability of the system. Secret references remain unaffected by this vulnerability.
Mitigation Recommendations
Upgrade OpenClaw to version 2026.8.1 or later where this issue is fixed. No other mitigation is required as the fix addresses the root cause by removing the inclusion of deterministic hashes in redacted configuration responses.
