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.

addresses: CWE-285 CWE-266

Documented procedures facilitate correct implementation and ongoing management of authorization decisions.

addresses: CWE-285 CWE-266

Periodic reviews identify and correct flaws in authorization decisions or enforcement.

addresses: CWE-285 CWE-266

Specifying access authorizations for each account and requiring approvals for account requests enforces proper authorization decisions.

addresses: CWE-266 CWE-285

The control requires explicit definition of separated access authorizations, making incorrect privilege assignments that bundle conflicting duties harder to implement.

addresses: CWE-266 CWE-285

Ensures privileges are assigned only as necessary rather than incorrectly over-granted.

addresses: CWE-285

The control's documentation requirement reduces improper authorization by ensuring only mission-justified actions bypass authentication.

addresses: CWE-285

Establishing permitted attributes and values, plus auditing changes, ensures authorization decisions are based on correctly managed policy data.

addresses: CWE-285

Explicitly mandates authorizing remote access types before permitting connections, directly mitigating improper authorization.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
T1098 Account Manipulation Persistence
Adversaries may manipulate accounts to maintain and/or elevate access to victim systems.
T1136 Create Account Persistence
Adversaries may create an account to maintain access to victim systems.
T1531 Account Access Removal Impact
Adversaries may interrupt availability of system and network resources by inhibiting access to accounts utilized by legitimate users.
Why these techniques?

Improper authorization in user management endpoints (add/update/delete) directly enables unauthorized account creation, modification, and removal, facilitating privilege escalation.

Confidence: MEDIUM · MITRE ATT&CK Enterprise v18.1

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.
