Deeper analysis
CVE-2026-2078 is an improper authorization vulnerability (CWE-266, CWE-285) in the yeqifu warehouse project, affecting its Permission Management component. The issue resides in the addPermission, updatePermission, and deletePermission functions within the file dataset/repos/warehouse/src/main/java/com/yeqifu/sys/controller/PermissionController.java. It impacts versions up to commit aaf29962ba407d22d991781de28796ee7b4670e4.
The vulnerability enables remote exploitation by an authenticated attacker with low privileges. Per its CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L), attacks require low complexity and no user interaction, allowing limited impacts on confidentiality, integrity, and availability through unauthorized permission manipulations.
The project uses a rolling release model, providing no specific version details for affected or updated releases. It was informed early via GitHub issue #55 but has not responded. An exploit is public and may be used, with details available in the repository at https://github.com/yeqifu/warehouse/, issue tracker entries, and VulDB at https://vuldb.com/?ctiid.344644 and https://vuldb.com/?id.344644.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces approved authorizations on the addPermission/updatePermission/deletePermission functions, blocking the unauthorized permission manipulations described in the CVE.
Restricts users to the minimum privileges required, preventing low-privilege authenticated attackers from reaching or abusing the vulnerable permission-management endpoints.
Ensures access-control decisions are made and enforced at runtime for each permission change request, mitigating the missing authorization checks in PermissionController.java.
