CVE-2026-42288Public exploitNetwork attack vector

Pre-authentication RCE via unsanitized database password

Published May 12, 2026 · Updated May 12, 2026

Code injection in the setup wizard in ChurchCRM before 7.3.2 allows remote attackers to execute arbitrary OS commands without authentication. The setup route copies raw DB_PASSWORD input into a single-quoted string in Config.php, letting an embedded quote and shell_exec call become executable PHP. The wizard must be reachable, but database credentials need not be valid because the file is written before validation and loaded on the next request as the web-server account.
