The\nmismatch dropped the `Content-Disposition: attachment` header, leaving Express to\nauto-render `.html`, `.svg`, and similar inline. The fix corrects the key case and\nadditionally forces `Content-Disposition: attachment` and\n`Content-Type: application/octet-stream` for any MIME type not on the preview\nallowlist.\n\n### Impact\nStored Cross-Site Scripting in the NocoDB origin from inline-rendered uploads. Script\nexecuting in the victim's browser can read the auth JWT from `localStorage`.\nExploitation requires authenticated upload permission and the secure-attachment mode\nto be enabled.\n\n### Credit\nThis issue was reported by @bugbunny-research.\nIt was independently reported by [@Davi","public_affected_ranges":["<= 0.301.3"]}],"null_published_at":"2026-11-04T10:04:27.930Z","source_updated_at":"2026-07-20T21:20:14.000Z","source_disclosed_at":"2026-06-17T14:07:52.000Z","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":"2026-11-04T02:47:44.783Z"}],"next_cursor":null,"snapshot_revision":"42594"}
