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.

    ## Summary In Nginx UI versions 2.5.0 through 2.5.x, the node-signature authentication path staged an attacker-controlled request body in a temporary file and synchronized it to disk before validating the body digest and cryptographic signature. An unauthenticated remote client that can reach the API can provide syntactically valid signature metadata and cause storage and I/O consumption before the request is rejected. ## Impact Concurrent malicious requests can consume temporary filesystem capacity, disk I/O, and request-processing resources, potentially disrupting Nginx UI and other services that share the filesystem. The issue affects availability only; it does not bypass authentication and does not provide confidentiality or integrity impact. Deployment-specific reverse-proxy body limits, filesystem quotas, and concurrency limits may reduce practical impact. ## Remediation Upgrade to Nginx UI 2.6.0 or later. The fix authenticates signed request metadata before staging the body and enforces an application-level streaming size limit with cleanup for rejected requests. Fix commit: https://github.com/0xJacky/nginx-ui/commit/8c9b9a1aff218ee6c980d047b750e49da3c46796
