CVE-2026-108963: Argument Injection (CVSS 8.8)

Description

databasement before 1.8.2 allows remote code execution because it runs certain commands (e.g., mariadb-dump) with a database name that can be specified by any authenticated user. For example, --result-file=/app/public/index.php can write to index.php. In other words, quoting prevents OS command injection in mariadb-dump, but the argument injection alone is sufficient for code execution indirectly. NOTE: the project's composer.json file does not indicate an independently published databasement Composer package.
