Changelog

Sourced from github.com/jackc/pgx/v4's changelog.

4.18.2 (March 4, 2024)

Fix CVE-2024-27289

SQL injection can occur when all of the following conditions are met:

1. The non-default simple protocol is used.
2. A placeholder for a numeric value must be immediately preceded by a minus.
3. There must be a second placeholder for a string value after the first placeholder; both must be on the same line.
4. Both parameter values must be user-controlled.

Thanks to Paul Gerste for reporting this issue.

Fix CVE-2024-27304

SQL injection can occur if an attacker can cause a single query or bind message to exceed 4 GB in size. An integer overflow in the calculated message size can cause the one large message to be sent as multiple messages under the attacker's control.

Thanks to Paul Gerste for reporting this issue.
