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.
This control enforces ownership-based restrictions on portable storage device use, directly implementing access control over media insertion into organizational systems.
Hardware write-protect enforces access control on critical resources (e.g., firmware) independent of software state.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Device lock enforces restricted access until re-authentication, directly reducing unauthorized use of active sessions.
Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions.
By automatically labeling outputs with security attributes, the control supports attribute-based enforcement and reduces exploitability of improper access control weaknesses.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.

Deeper analysisAI
CVE-2026-1061 is an unrestricted file upload vulnerability in xiweicheng TMS versions up to 2.28.0. The issue affects the Upload function within the file src/main/java/com/lhjz/portal/controller/FileController.java, where manipulation of the filename argument enables the upload of arbitrary files. This flaw is remotely exploitable and has been assigned CWE-284 (Improper Access Control) and CWE-434 (Unrestricted Upload of File with Dangerous Type), with 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).
An attacker with low privileges, such as an authenticated user, can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling the upload of malicious files that could lead to further compromise depending on server configuration.
