Technical Analysis
CVE-2026-34967 affects Adminer versions 5.3.0 through 5.4.2 when the sql-log plugin is enabled. The vulnerability allows an authenticated user to supply path traversal sequences in the ns parameter of plugins/sql-log.php, resulting in arbitrary file write of .sql files with attacker-controlled content to any writable directory on the host system.
Potential Impact
An attacker with authentication privileges can write arbitrary .sql files to any writable directory on the host. This could potentially lead to further compromise depending on the environment and file usage. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the need for authentication and limited impact scope.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the sql-log plugin and limit authenticated user privileges to reduce risk.
