CVE-2026-34968: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in vrana adminer
Description
Adminer versions prior to 5.4.3 contain a path traversal vulnerability in SQLite mode that allows authenticated users to delete arbitrary files writable by the PHP process. This occurs because the database-list drop action does not properly validate file extensions before deletion, enabling attackers to submit crafted relative file paths via the db[] parameter.

Technical Analysis
CVE-2026-34968 is a path traversal vulnerability in Adminer before version 5.4.3. The flaw exists in SQLite mode where the database-list drop action fails to validate file extensions before deleting files. An authenticated attacker can exploit this by submitting arbitrary relative file paths through the db[] parameter, resulting in arbitrary file deletion of any files writable by the PHP process.
Potential Impact
An attacker with authentication privileges can delete arbitrary files on the server that are writable by the PHP process. This can lead to denial of service or disruption of application functionality by removing critical files.
Mitigation Recommendations
No official patch or remediation level is currently confirmed. Users should upgrade to Adminer version 5.4.3 or later once available. Until then, restrict access to trusted users only and monitor for suspicious activity related to file deletions. Check the vendor advisory for updates on patches or official fixes.
