SCA: security update for code.vikunja.io/api (GHSA-jfmm-mjcp-8wq2)

high Tenable Cloud Security Plugin ID 439218

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1,
 `TaskAttachment.ReadOne()` queries attachments by ID only (`WHERE id = ?`), ignoring the task ID from the
 URL path. The permission check in `CanRead()` validates access to the task specified in the URL, but
 `ReadOne()` loads a different attachment that may belong to a task in another project. This allows any
 authenticated user to download or delete any attachment in the system by providing their own accessible
 task ID with a target attachment ID. Attachment IDs are sequential integers, making enumeration trivial.
 Version 2.2.1 patches the issue. (CVE-2026-33678)

Solution

Update the code.vikunja.io/api library and its related packages to version 2.2.1 or later.
