## Overview

### Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-88f6-4rjv-x774. This link is maintained to preserve external references.

### Original Description
Vikunja before 2.6.0 continues to expose the raw TOTP shared secret after enrollment through the GET /api/v1/user/settings/totp and /api/v1/user/settings/totp/qrcode endpoints without re-authentication. Attackers with a valid access token can read the secret, import it into their own authenticator, and generate valid codes indefinitely to defeat the second factor and enable account takeover.

## Affected packages

- `code.vikunja.io/api <= 2.5.0`

## Remediation

Refer to the advisory for the patched release.
