The normal MIME streaming path enforces those options in `MimeNode._getStream()`. However, `jsonTransport` serializes messages by calling `mail.normalize()`, which resolves `html`, `text`, alternatives, calendar events, and attachments through `shared.resolveContent()` before MIME generation. `shared.resolveContent()` reads local files and fetches HTTP(S) URLs directly, without receiving or checking `disableFileAccess` or `disableUrlAccess`.\n\nAs a result, applications that use `jsonTransport` as a safe serializer or queue payload generator while relying on `disableFileAccess` / `disableUrlAccess` can still be made to read local files into the generated JSON output or make outbound HTTP requests when an attacker controls message content fields such as attachment `path` or `text.href`.\n\nThe same missing-enforcement root cause is also reachable before normal streaming when `attachDataUrls` causes `_convertDataImages()` to call `mail.resolveContent(mail.data, 'html', ...)`; this should be fixed with the same acce","public_affected_ranges":["<= 8.0.8"]}],"null_published_at":"2026-11-07T07:07:39.858Z","source_updated_at":"2026-06-15T17:35:12.000Z","source_disclosed_at":"2026-06-15T17:35:10.000Z","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":"2026-11-06T15:12:54.193Z"}],"next_cursor":null,"snapshot_revision":"42594"}
