CVE-2026-3065
Published: 24 February 2026
Summary
CVE-2026-3065 is a medium-severity Injection (CWE-74) vulnerability in Hummerrisk Hummerrisk. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unix Shell (T1059.004); ranked in the top 2.4% 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
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.
