CVE-2026-35657 is a high-severity Incorrect Authorization (CWE-863) vulnerability in Openclaw Openclaw. Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 14th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

Vulnerability Data
OpenClaw before 2026.3.25 contains an authorization bypass vulnerability in the HTTP /sessions/:sessionKey/history route that skips operator.read scope validation. Attackers can access session history without proper operator read permissions by sending HTTP requests to the vulnerable endpoint.

Why these techniques?
Authorization bypass in public HTTP endpoint directly enables exploitation of public-facing application (T1190) to access restricted session history data.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces the missing operator.read scope check on the /sessions/:sessionKey/history endpoint before returning session data.
Ensures the operator.read privilege is the minimum required to access session history, limiting impact if authorization is bypassed.
Enforces information flow rules that would block unauthorized reads of session history objects lacking the required scope attribute.

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.
Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.
By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
