Summary

Adminer before 6.1.1 contains a code injection flaw (CWE-94) that lets authenticated SQLite users bypass ATTACH and VACUUM INTO restrictions by prefixing statements with a UTF-8 byte-order mark. An attacker with valid credentials can attach a database file at a PHP-served path and create a table named with PHP code, which runs as the web server user. The CVSS 4.0 vector requires high privileges and no user interaction, and it rates the impact on confidentiality, integrity and availability as high. CISA's SSVC assessment rates exploitation as poc, and the vulnerability is not listed in CISA KEV.
