CVE-2026-27178

21
FAUCET Score

CVE-2026-27178 describes a stored cross-site scripting (XSS) vulnerability in MajorDoMo (Major Domestic Module) that allows unauthenticated attackers to inject malicious scripts into the shoutbox via method parameter injection. This medium-severity vulnerability (CVSS 6.1) can lead to session hijacking and cookie exfiltration when an administrator views the dashboard, as the injected script executes automatically due to a lack of sanitization. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
