CVE-2026-53848 is a low-severity Incomplete List of Disallowed Inputs (CWE-184) vulnerability in Openclaw Openclaw. Its CVSS base score is 2.3 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Indirect Command Execution (T1202); ranked at the 8th 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 SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data
OpenClaw before 2026.5.26 contains an exec allowlist bypass vulnerability allowing authenticated operators to execute wrapper-level side effects outside allowlisted command intent. Attackers can craft command requests that bypass allowlist validation by leveraging transparent command wrappers to perform unintended operations.

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces the command allowlist policy so that only intended operations are executed, blocking the wrapper bypass.
Requires validation of command inputs to reject crafted requests that evade allowlist checks via transparent wrappers.
Restricts the system to only the minimal set of authorized commands, reducing the attack surface for wrapper-level side effects.

Secure SDLC practices directly require complete, positive input validation instead of incomplete denylists.

Security testing can discover missing input checks, but does not prevent the weakness during development.
Application security requirements can mandate complete input validation rules, but the control itself does not prescribe how to build those rules.
Secure architecture principles include robust input validation design, yet the control is broader than this single weakness.
Secure coding standards directly require exhaustive allow-lists or complete deny-lists for inputs, addressing the root cause of incomplete disallowed-input lists.
