## Overview

In version 0.3.32 of open-webui, the application uses a vulnerable version of the starlette package through its dependency on fastapi. The starlette package versions <=0.49 are susceptible to uncontrolled resource consumption, which can be exploited to cause a denial of service through memory exhaustion. This issue is addressed in fastapi version 0.115.3.

## Affected packages

- `open-webui < 0.5.8`

## Remediation

Upgrade to a patched release:

- `open-webui 0.5.8`
