Short explanation
Vikunja contains a permissive CORS configuration that trusts every localhost and 127.0.0.1 port with credentials, even when service.publicurl is set. Attackers controlling a page on any localhost port can send a credentialed request to the token refresh endpoint and read the returned bearer JWT to take over the logged-in user's account.
An unauthorized attacker stealing a user session token directly leads to account compromise. Sources conflict regarding the CVSS base score.
What should be done?
- Upgrade to version 2.7.0 or later where unaffected
- Follow vendor advisories for updates

Saldırganlar token yenileme uç noktasına istek göndererek dönen bearer JWT değerini okuyabilir ve hesap ele geçirme işlemi gerçekleştirebilir.
CVSS taban puanı ve vektörü konusunda cvelist ve nvd kaynakları arasında farklılıklar bulunmaktadır.
