The lettre library through 0.10.0-alpha for Rust allows arbitrary sendmail option injection via transport/sendmail/mod.rs.

 https://cve.radiocsirt.org/vuln/rustsec-2020-0069 RUSTSEC-2020-0069 — Argument injection in sendmail transport 2026-10-13T04:54:30.149054+00:00

Affected: crates.io: lettre

Affected versions of lettre allowed argument injection to the sendmail command. It was possible, using forged `to` addresses, to pass arbitrary arguments to the sendmail executable.

Depending on the implementation (original sendmail, postfix, exim, etc.) it could be possible in some cases to write email data into arbitrary files (using sendmail's logging features). The flaw is corrected by modifying the executed command to stop parsing arguments before passing the destination addresses.

NOTE: This vulnerability only affects the `sendmail` transport. Others, including `smtp`, are not affected.
