Machine-written summary

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

Diesel versions before 2.3.8 are vulnerable to command injection in their handling of PostgreSQL COPY FROM and COPY TO statements. Options passed as strings or characters are not checked for quote characters, so an attacker who can influence those values can inject extra options into the statement, though not additional statements. Upgrade to Diesel 2.3.8 or newer, which escapes quotes in the provided arguments.
