Hubzilla version prior to 11.4 CSRF via OAuth2 /authorize Endpoint App Registration

Hubzilla versions prior to 11.4 contains a cross-site request forgery vulnerability in the OAuth2 /authorize endpoint handled by Zotlabs\Module\Authorize::post() that allows unauthenticated attackers to register arbitrary OAuth2 applications under an authenticated user's account by submitting a cross-origin POST request without CSRF token or Origin/Referer validation. Attackers can craft a malicious HTML form that autosubmits attacker-chosen OAuth2 parameters including client_id, client_secret, redirect_uri, and scope to silently register a persistent OAuth2 application, enabling interception of future OAuth2 authorization codes when the victim later authenticates against the attacker-controlled client.

Multiple Cross-Site Scripting (XSS) vulnerabilities in Hubzilla 7.0.3 and earlier allows remote attacker to include arbitrary web script or HTML via the rpath parameter.

A PHP Local File Inclusion vulneraility in the default Redbasic theme for Hubzilla before version 7.2 allows remote attackers to include arbitrary php files via the schema parameter.
