CVE-2026-34968 · Severity: high · CVSS 8.1 · Published 2026-08-25

Adminer is a web-based database management tool that supports multiple database systems including SQLite. An authenticated attacker can delete arbitrary files on the web server by submitting specially crafted file paths through the database drop feature, potentially causing data loss or system compromise if the PHP process has write access to sensitive files.

## 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.
