CVE-2026-57517 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Control Web Panel before 0.9.8.1225 contains a blind SQL injection vulnerability that allows unauthenticated remote attackers to execute arbitrary SQL queries by submitting unsanitized input through the userRes POST parameter at the user endpoint. Attackers can exploit MySQL root privileges obtained via the injection to write arbitrary files using INTO DUMPFILE, enabling deployment of a PHP webshell to the web-accessible roundcube logs directory and achieving remote code execution as the cwpsvc account.. EPSS estimates a 0.58% chance of exploitation in the next 30 days.
