Technical details
The vulnerability is a path traversal and arbitrary file deletion flaw in Adminer's SQLite database handler. The drop_databases() function accepts user-submitted file paths from POST parameter db[] and passes them directly to PHP's unlink() function without validating the file extension or path, whereas the create and rename operations properly validate that files have .db, .sdb, or .sqlite extensions. An authenticated attacker with a valid CSRF token can submit arbitrary relative paths in the db[] parameter to delete any file writable by the PHP process. The attack requires authentication but no additional user interaction, and affects SQLite mode specifically.
