An SQL injection vulnerability has been discovered in the Courier Authentication Library.

2.  Impact Information


The Courier Authentication Library is a generic authentication API that encapsulates the process of validating account passwords.


It has been reported that some parameters used in SQL queries are not properly sanitized before being processed when using a non-Latin locale Postgres database.


A remote attacker could send specially crafted input to an application using the library, possibly resulting in the execution of arbitrary SQL commands.

There is no known workaround at this time.


All Courier Authentication Library users should upgrade to the latest version:
