What is CVE-2026-43528?

OpenClaw versions before 2026.4.14 are susceptible to a redaction bypass vulnerability that can be exploited by authenticated gateway clients. This flaw allows these clients to access unredacted secrets through the sourceConfig and runtimeConfig alias fields, potentially revealing sensitive information including provider API keys and gateway authentication data. Attackers who possess config read access have a pathway to obtain credentials that should be securely redacted.
