Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

chasquid versions before 1.13 are vulnerable to SMTP smuggling because the server accepts lines terminated only by LF. The source gives few details on the exact conditions, but the flaw is described as letting an attacker smuggle SMTP messages past the server's parsing. Upgrade github.com/albertito/chasquid to version 1.13 or later.
