Vulnerability Data
OpenClaw before 2026.4.14 contains a redaction bypass vulnerability that allows authenticated gateway clients to receive unredacted secrets through sourceConfig and runtimeConfig alias fields. Attackers with config read access can exploit this to obtain provider API keys, gateway authentication material, and…

Why these techniques?
Redaction bypass directly exposes credentials (API keys, auth material) stored in application config, enabling T1552 Unsecured Credentials access for users with read permissions.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces filtering of sensitive information (API keys, credentials) from configuration outputs such as sourceConfig/runtimeConfig alias fields.
Prevents unauthorized information flows by ensuring redaction policies are applied before secrets are released to gateway clients.
Enforces access decisions that should restrict release of unredacted secrets to only those principals explicitly authorized to view them.

Explicit information-deletion control directly addresses improper removal of sensitive data.
Data-masking techniques can substitute for removal when full deletion is impractical.
Test-data protection rules require sanitization of production data used in testing.
Classification identifies sensitive data that must be removed before storage or transfer.
Information-transfer rules can require sanitization of sensitive content before sharing.
PII-protection requirements include removing identifiers before storage or disclosure.
