This link is maintained to preserve external references.\n\n### Original Description\nVikunja before 2.6.0 fails to apply pixel decode limits to avatar and project-background upload endpoints, allowing authenticated users to upload crafted images that decode to excessive pixel counts. Attackers can upload small images with extreme aspect ratios that consume significant CPU and memory during processing, causing denial of service through repeated or concurrent uploads.","public_affected_ranges":["<= 2.5.0"]}],"null_published_at":"2026-11-01T01:03:56.603Z","source_updated_at":"2026-10-09T20:52:11.000Z","source_disclosed_at":"2026-09-15T18:32:30.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T23:14:22.124Z"}],"next_cursor":null,"snapshot_revision":"42594"}
