Threat & Defense at a Glance
Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Documented procedures facilitate correct implementation and ongoing management of authorization decisions.
Periodic reviews identify and correct flaws in authorization decisions or enforcement.
Specifying access authorizations for each account and requiring approvals for account requests enforces proper authorization decisions.
The control requires explicit definition of separated access authorizations, making incorrect privilege assignments that bundle conflicting duties harder to implement.
Ensures privileges are assigned only as necessary rather than incorrectly over-granted.
The control's documentation requirement reduces improper authorization by ensuring only mission-justified actions bypass authentication.
Establishing permitted attributes and values, plus auditing changes, ensures authorization decisions are based on correctly managed policy data.
Explicitly mandates authorizing remote access types before permitting connections, directly mitigating improper authorization.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Improper authorization in user management endpoints (add/update/delete) directly enables unauthorized account creation, modification, and removal, facilitating privilege escalation.
NVD Description
A weakness has been identified in yeqifu warehouse up to aaf29962ba407d22d991781de28796ee7b4670e4. Affected by this vulnerability is the function addUser/updateUser/deleteUser of the file dataset\repos\warehouse\src\main\java\com\yeqifu\sys\controller\UserController.java of the component User Management Endpoint. This manipulation causes improper authorization. The attack can be initiated remotely.…

Deeper analysisAI
CVE-2026-2076 is an improper authorization vulnerability affecting the yeqifu/warehouse project up to commit aaf29962ba407d22d991781de28796ee7b4670e4. The issue resides in the User Management Endpoint, specifically the addUser, updateUser, and deleteUser functions within the file dataset\repos\warehouse\src\main\java\com\yeqifu\sys\controller\UserController.java. This flaw, linked to CWE-266 (Incorrect Privilege Assignment) and CWE-285 (Improper Authorization), enables unauthorized manipulation of user operations.
The vulnerability can be exploited remotely over the network with low attack complexity and requires low privileges (PR:L), as indicated by 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). An attacker with initial low-privileged access could invoke these endpoints to achieve limited impacts on confidentiality, integrity, and availability, such as unauthorized user additions, modifications, or deletions. A public exploit is available, increasing the risk of attacks.
Advisories note that yeqifu/warehouse employs continuous delivery with rolling releases, so no specific affected or patched versions are detailed. The project was notified early via GitHub issue #53 but has not responded as of the CVE publication on 2026-02-07.
Notable context includes the public availability of the exploit, which could facilitate real-world attacks, though no evidence of active exploitation is reported.
