## Overview

Unrestricted Upload of File with Dangerous Type vulnerability in Apache Answer.

This issue affects Apache Answer: through 2.0.0.

The server did not sufficiently validate user-supplied image URLs, allowing arbitrary external content to be embedded as profile images, which could expose users to unintended external requests and tracking by third-party servers.
Users are recommended to upgrade to version 2.0.1, which fixes the issue.

## Affected packages

- `github.com/apache/incubator-answer < 1.7.2-0.20260511040518-11091244f64e`

## Remediation

Upgrade to a patched release:

- `github.com/apache/incubator-answer 1.7.2-0.20260511040518-11091244f64e`
