This link is maintained to preserve external references.\n\n### Original Description\nVikunja 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.\n\n## Affected packages\n\n- `code.vikunja.io/api >= 2.5.0, < 2.6.0`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"twilight","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
