Summary

CVE-2026-3065 is a medium-severity Injection (CWE-74) vulnerability in Hummerrisk Hummerrisk. Its CVSS base score is 5.3 (Medium).

Operationally, ranked in the top 5% of CVEs by exploit likelihood; 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 SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

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

CVE-2026-3065 is a command injection vulnerability affecting HummerRisk versions up to 1.5.0. The flaw resides in the CommandUtils.commonExecCmdWithResult function within the CloudTaskService.java file of the Cloud Task Dry-run component. It stems from improper validation of the fileName argument, enabling attackers to inject and execute arbitrary commands.

Remote exploitation is possible with low complexity over the network, requiring low privileges (PR:L) and no user interaction. Per the CVSS v3.1 score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L), attackers with authenticated low-privilege access can achieve limited impacts on confidentiality, integrity, and availability through injected commands.

Advisories note that the exploit is public and may be used, as detailed in a GitHub issue at https://github.com/AnalogyC0de/public_exp/issues/9 and VulDB entries at https://vuldb.com/?ctiid.347416, https://vuldb.com/?id.347416, and https://vuldb.com/?submit.757696. The vendor was contacted early about the disclosure but provided no response, and no patches or mitigations are specified.

The vulnerability, linked to CWE-74 and CWE-77, was published on 2026-02-24, with a publicly available exploit heightening the risk of real-world abuse.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 Information Input Validation good match

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles include proper neutralization and safe command construction practices.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches injection vulnerabilities before release.

A.8.16 Monitoring activities partial match
finds

Monitoring activities can identify active injection attacks after they occur.

A.8.28 Secure coding partial match
prevents

Secure coding standards require proper neutralization of special elements, directly addressing CWE-74.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-74, a class-level weakness, and none of its children carries one either.
  • No fine-grained STIG row for CWE-77, a class-level weakness, and none of its children carries one either.
