DescriptionCVE.org

OpenClaw before 2026.3.22 contains an information disclosure vulnerability that allows attackers with operator.read scope to expose credentials embedded in channel baseUrl and httpUrl fields. Attackers can access gateway snapshots via config.get and channels.status endpoints to retrieve sensitive authentication information from URL userinfo components.

AnalysisAI

Credential exposure in OpenClaw gateway snapshots enables authenticated attackers with operator.read scope to extract embedded authentication tokens from channel configuration URLs. Attackers query config.get and channels.status API endpoints to retrieve gateway snapshots containing credentials in URL userinfo components of baseUrl and httpUrl fields. Affects OpenClaw versions prior to 2026.3.22. Authentication required (PR:L); no public exploit identified at time of analysis.

Technical ContextAI

CWE-312 cleartext storage of sensitive information. Credentials embedded directly in URL userinfo components (e.g., https://user:pass@host) within channel configuration objects. API endpoints expose complete gateway state snapshots to low-privileged authenticated users without credential redaction, violating principle of least privilege for configuration data access.

RemediationAI

Vendor-released patch: upgrade to OpenClaw version 2026.3.22 or later. Upstream fixes implement credential sanitization in gateway snapshot responses (commits 630f1479c44f78484dfa21bb407cbe6f171dac87 and f0202264d0de7ad345382b9008c5963bcefb01b7). Immediately audit existing channel configurations to remove credentials from baseUrl/httpUrl fields; migrate to dedicated authentication mechanisms (API keys, OAuth tokens) stored outside URL structures. Review operator.read scope assignments and restrict to minimum necessary personnel. Rotate any credentials potentially exposed through historical snapshot queries.
