Detailsinfo

A vulnerability classified as problematic was found in 0xJacky Nginx UI up to 2.5.x. This vulnerability affects some unknown processing of the component Node-Signature Authentication Path. The manipulation with an unknown input leads to a temp file vulnerability. The CWE definition for the vulnerability is CWE-377. Creating and using insecure temporary files can leave application and system data vulnerable to attack. As an impact it is known to affect availability. CVE summarizes:

Nginx UI is a web user interface for the Nginx web server. From 2.5.0 until 2.6.0, the node-signature authentication path performs temporary file staging of an attacker-controlled request body and synchronizes it before validating the body digest and cryptographic signature. An unauthenticated remote client that can reach the API and provide syntactically valid signature metadata can consume temporary filesystem capacity, disk input and output, and request-processing resources before rejection. The issue affects availability and does not bypass authentication or provide confidentiality or integrity impact. This issue is fixed in version 2.6.0.

The advisory is available at github.com. This vulnerability was named CVE-2026-107805 since 10/08/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. The technical details are unknown and an exploit is not available.

Upgrading to version 2.6.0 eliminates this vulnerability.
