Summary

Duplicate Advisory: Vikunja: Planka migration retains an unbounded aggregate of attacker-served attachments and can OOM the API

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-wq92-8x3r-fm38. This link is maintained to preserve external references.

Original Description

Vikunja versions before 2.6.0 contain a resource exhaustion vulnerability in the Planka migrator that fails to enforce aggregate memory budgets during migration jobs. Authenticated attackers can submit migration requests pointing to attacker-controlled servers advertising numerous size-compliant attachments, exhausting worker memory and causing denial of service for all users.
