diesel is vulnerable to SQL injection
78
High Risk
This Affects:
dieselTL;DR
The PostgreSQL COPY option path builds DEFAULT, NULL, DELIMITER, QUOTE, and ESCAPE text using quoted literals because binds are not available there, so an embedded single quote in a supplied option can break out of the string and change the COPY statement structure; the update escapes those quotes and handles delimiter, quote, and escape bytes that are single-quote characters. The same release also fixes several unsound or platform-API misuse issues around SQLite, MySQL, and PostgreSQL value and connection code, such as SqliteValue text and blob reading, Debug/Display and batch insert formatting, and alignment and call-order mistakes that could read padding bytes, leak memory, or expose undefined behavior. Together these changes make validation-time SQL construction and deserialization paths consistent with the documented safety of the public API.
