XSS in Vrana Adminer
CVE-2026-100695
Adminer before 6.0.2 contains a cross-site scripting vulnerability where the CONNECTION_ID() database result is interpolated into JavaScript without proper escaping, allowing a malicious database server to execute arbitrary JavaScript in the authenticated Adminer origin. In co-located deployments where the database has FILE privileges and can write to the webroot, attackers can use the XSS to submit authenticated SQL requests that write PHP files via INTO DUMPFILE, achieving remote code execution as the web server account.
