Description Laura Pardo 2018-03-07 20:53:48 UTC
The sqlauth module in SimpleSAMLphp before 1.15.2 relies on the MySQL utf8 charset, which truncates queries upon encountering four-byte characters. There might be a scenario in which this allows remote attackers to bypass intended access restrictions.

CVE-2018-6521 (SSPSA 201801-03) is for the SimpleSAMLphp application not the php-simplesamlphp/saml2 library
