# Qt Network: HTTP response handling can consume uncontrolled resources

Link for people: https://infrastack.ai/live/CVE-2026-116337 (this .md is for agents)

The Qt Framework's Network module mishandles HTTP responses in a way that lets a remote server consume uncontrolled resources on the client. An attacker can cause excess memory or CPU use in an application that fetches data over HTTP.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the application uses the Qt Network module (QNetworkAccessManager) to make HTTP requests.
- Check the Qt version in use, for example with `qmake --version` or the Qt version in the build configuration.

## From the sources

Uncontrolled resource consumption vulnerability in the Qt Framework HTTP response handling functionality of the Qt Network module.
