CVE-2026-73849 Detail

Description

Emlog is an open source website building system. In 2.6.26 and earlier, install.php accepts action=reinstall without authentication and deliberately skips the already-installed check because the guard runs only when $act != 'reinstall'. A remote attacker can submit hostname, dbuser, dbpasswd, dbname, dbprefix, username, password, and email values to cause file_put_contents('config.php', $config) to overwrite the configuration with attacker-controlled database settings and create a new administrator account. No fixed version is available as of this review.
