CRITICAL 9.8EPSS 3.05%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.05%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
