CVE-2026-33030: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in 0xJacky nginx-ui
CVE-2026-33030 affects nginx-ui versions 2. 3. 3 and earlier, where an Insecure Direct Object Reference (IDOR) vulnerability allows any authenticated user to access, modify, or delete resources belonging to other users. This occurs because the application's base Model struct lacks a user_id field, and resource endpoints do not verify user ownership, resulting in complete authorization bypass in multi-user environments. No patches are publicly available at this time. The vulnerability has a high severity with a CVSS score of 8. 8.
AI Analysis
Technical Summary
The vulnerability in nginx-ui (<= 2.3.3) arises from improper authorization checks due to missing user ownership verification on resource endpoints. The base Model struct does not include a user_id field, causing all resource queries by ID to be insufficiently protected. This enables authenticated users to bypass authorization controls and perform unauthorized access, modification, or deletion of other users' resources. The issue is categorized under CWE-78 (OS Command Injection) and CWE-639 (Authorization Bypass Through User-Controlled Key). No official patches or fixes are currently available.
Potential Impact
Successful exploitation allows any authenticated user to fully bypass authorization controls and access, modify, or delete resources of other users within the nginx-ui application. This can lead to complete compromise of data confidentiality, integrity, and availability in multi-user deployments. The CVSS score of 8.8 reflects high impact on confidentiality, integrity, and availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to trusted users only and consider limiting multi-user deployments or applying compensating controls such as network segmentation or additional authentication layers. Monitor vendor channels for updates and apply patches promptly once available.
