CVE-2026-100543 PUBLISHED

OpenClaw before 2026.8.1 Information Disclosure via Configuration Hash

Assigner: VulnCheck
Reserved: 26.09.2026 Published: 26.09.2026 Updated: 26.09.2026

OpenClaw (npm package openclaw) before 2026.8.1 could include deterministic hashes computed over the original, unredacted configuration in redacted configuration responses. When the Gateway password had low entropy and the remaining configuration values were reconstructable, these hashes acted as offline password verifiers: a caller able to obtain the redacted configuration (for example via config.get) could test password candidates offline without going through the rate-limited Gateway authentication path. Recovering the password could grant the documented shared-secret operator authority. Secret references were not affected in the same way. The issue is fixed in 2026.8.1.
