Summary

CVE-2026-41392 is a medium-severity Incomplete List of Disallowed Inputs (CWE-184) vulnerability in Openclaw Openclaw. Its CVSS base score is 5.4 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 2th 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 SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2026-41392, published on 2026-04-28, affects OpenClaw versions before 2026.3.31 and involves an exec allowlist bypass vulnerability. Attackers can inherit allowlist trust via shell init-file wrapper invocations, exploiting shell options such as --rcfile, --init-file, and --startup-file to load attacker-chosen initialization files while evading exec allowlist matching restrictions. The issue carries a CVSS v3.1 base score of 6.7 (AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H) and maps to CWE-184.

Local attackers with low privileges (PR:L) can exploit this vulnerability, though it requires high attack complexity (AC:H) and user interaction (UI:R), such as tricking a user into invoking the affected shell options. Successful exploitation bypasses the exec allowlist, enabling high-impact outcomes including unauthorized access to confidential data, modification of system integrity, and disruption of availability.

Mitigation details are outlined in official advisories, including the OpenClaw GitHub security advisory (GHSA-wpc6-37g7-8q4w), a patch commit (0c8375424620e12777ef24c162eedc7e9fcfd7e3), and a VulnCheck advisory. Updating to OpenClaw 2026.3.31 or later addresses the vulnerability by resolving the allowlist bypass.

Mitigating Controls (NIST 800-53 r5) AI

SI-10 requires validity checks on inputs, which structurally replaces incomplete deny-lists with complete allow-list or sanitization logic.

finds

Security testing can discover missing input checks, but does not prevent the weakness during development.

prevents

Application security requirements can mandate complete input validation rules, but the control itself does not prescribe how to build those rules.

prevents

Secure architecture principles include robust input validation design, yet the control is broader than this single weakness.

prevents

Secure coding standards directly require exhaustive allow-lists or complete deny-lists for inputs, addressing the root cause of incomplete disallowed-input lists.
