Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 21.4th 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 are NIST 800-53 AC-3 (Access Enforcement) and AC-6 (Least Privilege).
Deeper analysis
CVE-2026-0574 is an improper authorization vulnerability in the yeqifu warehouse project, affecting versions up to commit aaf29962ba407d22d991781de28796ee7b4670e4. The weakness is located in the saveUserRole function of the file warehouse\src\main\java\com\yeqifu\sys\controller\UserController.java within the Request Handler component. Published on 2026-01-04, it is associated with CWEs CWE-266 and CWE-285, and carries a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).
The vulnerability enables remote exploitation by an authenticated attacker with low privileges. Exploitation of the saveUserRole function allows vertical privilege escalation, potentially granting unauthorized access to elevate user roles and resulting in low-level impacts to confidentiality, integrity, and availability.
Advisories referenced in GitHub repositories detail the vertical privilege escalation vulnerability and provide a public proof-of-concept exploit. VulDB entries confirm the remote attack vector and public availability of the exploit. The project employs a rolling release strategy for continuous delivery, preventing specification of exact affected or patched versions, with no further mitigation details outlined in the sources.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces authorization decisions on the saveUserRole function to block unauthorized role modifications by low-privilege users.
Restricts users to the minimum privileges required, preventing the vertical escalation that occurs when saveUserRole can be abused.
Manages user role assignments and account privileges so that only authorized administrators can invoke saveUserRole.
