## Affected

- stangirard stangirard/quivr: version range not reported
- quivr-core (PyPI): through 0.0.14

## Description

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.

## What to do
