# Vikunja: world-readable storage files let local users read data

Link for people: https://infrastack.ai/live/CVE-2026-123505 (this .md is for agents)

Vikunja before 2.7.1 creates storage blobs with world-readable file permissions. A local user on the same machine can read attachments, project backgrounds, exports and the SQLite database, then crack password hashes offline.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the Vikunja version with `vikunja version` or the release tag in your deployment
- Inspect permissions on the Vikunja files directory and SQLite database with `ls -l` and confirm they are not world-readable

## Fix

- Vikunja: move to `2.7.1` or later

- [advisory] Vendor advisory: github.com https://github.com/go-vikunja/vikunja/security/advisories/GHSA-9rfw-7hv4-3vv3

## From the sources

Vikunja before 2.7.1 contains an insecure file permissions vulnerability that allows local users to read stored data because localStorage.Write creates blobs world-readable. Local attackers on a shared host can read attachments, project backgrounds and exports, and copy the SQLite database to crack password hashes offline.
