## Overview

A Denial of Service (DoS) vulnerability in the file upload feature of stangirard/quivr v0.0.298 allows unauthenticated attackers to cause excessive resource consumption by appending characters to the end of a multipart boundary in an HTTP request. This leads to the server continuously processing each character, rendering the service unavailable and impacting all users.

## Affected packages

- `quivr-core <= 0.0.14`

## Remediation

Refer to the advisory for the patched release.
