What's Changed

• Strip control characters (CR/LF) from attachment filenames and from decoded header parameter and MIME-encoded-word values -- thanks @iliaal
• Add configurable limits to MIME parsing, each recording a parse error when reached (override via DI config) -- thanks @iliaal:
  • maxMimePartDepth (default 256) — maximum multipart nesting depth
  • maxHeaderCount (default 1000) — maximum headers per part
  • maxHeaderSizeBytes (default 1048576) — maximum total header bytes per part
• Append child parts in O(n) rather than O(n²) -- thanks @iliaal
• Generate MIME boundaries with random_bytes() -- thanks @iliaal

Security

This release fixes two privately reported vulnerabilities:

• GHSA-36h5-qg4p-q2qf -- CRLF header injection via attachment filename.
• GHSA-f6v3-2qmr-vfjx -- uncontrolled resource consumption (CPU/memory) when parsing untrusted MIME.

Found and reported privately by @iliaal, who also proposed fixes that informed the patches. Upgrading is recommended.
