Summary

CVE-2026-32975 is a medium-severity Reliance on Untrusted Inputs in a Security Decision (CWE-807) vulnerability in Openclaw Openclaw. Its CVSS base score is 6.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 26th 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-24 (Access Control Decisions) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-32975 is a weak authorization vulnerability (CWE-807) affecting OpenClaw versions before 2026.3.12, specifically in Zalouser allowlist mode. The flaw occurs because authorization checks match mutable group display names rather than stable group identifiers, enabling bypasses of intended restrictions. It carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its network accessibility, low attack complexity, and lack of prerequisites.

Unauthenticated attackers can exploit this vulnerability remotely without user interaction. By creating groups with display names identical to those in the Zalouser allowlist, they bypass channel authorization controls and route messages from unintended groups to the agent. This could allow unauthorized message injection or exfiltration, compromising confidentiality, integrity, and availability as reflected in the high CVSS impact metrics.

Mitigation details are available in the referenced advisories, including the OpenClaw security advisory at https://github.com/openclaw/openclaw/security/advisories/GHSA-f5mf-3r52-r83w and VulnCheck analysis at https://www.vulncheck.com/advisories/openclaw-weak-authorization-via-mutable-group-names-in-zalouser-allowlist. OpenClaw 2026.3.12 addresses the issue by using stable identifiers for authorization.

Mitigating Controls (NIST 800-53 r5) AI

Explicitly requires that every access decision be based on authoritative, protected decision data rather than caller-supplied inputs.

Input validation can reject malformed or attacker-controlled values before they reach a security decision point.

Access enforcement requires decisions to be made from trusted policy data rather than modifiable client-supplied inputs.

Information-flow enforcement applies rules to validated, internal attributes instead of untrusted external values.

PR.AA-03 mostly match
prevents

Strong authentication mechanisms directly prevent security decisions from depending on modifiable, untrusted inputs.

PR.AA-04 mostly match
prevents

Verification and protection of identity assertions stops reliance on attacker-controlled values for authorization decisions.

PR.AA-01 partial match
prevents

Proper management of identities/credentials reduces the chance that security decisions will be driven by untrusted inputs.

PR.AA-05 partial match
prevents

Policy-driven, least-privilege authorization reduces opportunities to bypass controls via tampered inputs.

prevents

Secure coding standards directly prohibit using untrusted inputs for security-critical decisions.

finds

Security testing in development catches input-validation flaws before deployment.

finds

Monitoring can detect exploitation but does not stop the underlying weakness.

prevents

Application security requirements explicitly call for validation of inputs used in security decisions.

prevents

Secure architecture principles mandate treating all external inputs as untrusted.

prevents

Access-control rules can be bypassed if they rely on untrusted inputs.
