    CVE-2018-6521

    Published: 2 Feb 2018Last Modified: 8 Jul 2026

    Summary:

    Details: 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.
