Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Andy Moyle Church Admin allows Stored XSS.This issue affects Church Admin: from n/a through 4.4.4.
The Church Admin WordPress plugin before 3.4.135 does not have authorisation and CSRF in some of its action as well as requested files, allowing unauthenticated attackers to repeatedly request the "refresh-backup" action, and simultaneously keep requesting a publicly accessible temporary file generated by the plugin in order to disclose the final backup filename, which can then be fetched by the attacker to download the backup of the plugin's DB data
