Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2018-6521 not yet assigned priority: Debian including 1 source packages (simplesamlphp), 4 status rows across 4 suites (bookworm, bullseye, forky, sid): resolved 4.
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.
