Songloft 2.9.0 before 2.13.6 contains a hardcoded credentials vulnerability that allows adjacent network attackers to authenticate as administrator using the fixed admin/admin pair. Attackers on the same network can log in via the /api/v1/auth/login endpoint to modify library and configuration settings and install JavaScript plugins running in QuickJS.
