# File and import security Attachment uploads use a managed data root, validated metadata, size/type/signature checks, and safe download paths. Parser decoding is isolated and resource-bounded. URL import validates destinations and rejects unsafe redirects; DNS rebinding and actual socket binding remain a documented verification concern. Generated CV previews are sandboxed and public CV/PDF links are random, revocable, noindex, and rate-limited. Never log or document private file contents, connection strings, or bearer tokens.
