CVE-2026-100695

Adminer before 6.0.2 XSS via CONNECTION_ID escalating to RCE

Published: Sep 26, 2026Updated: Sep 26, 2026 Sources: CVE List NVDCWE-79

6.1MEDIUM

Description

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.
