Synopsis

The /bin/Objects.php endpoint is vulnerable to CSRF

This endpoint allows remote attackers to perform actions on Objects with the permissions of a victim user, provided the victim user has an active session and is induced to trigger the malicious request.

--- 

The /bin/Snippets.php/ endpoint is vulnerable to CSRF

This endpoint allows remote attackers to perform actions on Snippets with the permissions of a victim user, provided the victim user has an active session and is induced to trigger the malicious request.

This endpoint allows remote attackers to perform actions on user settings with the permissions of a victim user, provided the victim user has an active session and is induced to trigger the malicious request.

This endpoint allows remote attackers to arbitrary files with the permissions of a victim user, provided the victim user has an active session and is induced to trigger the malicious request. While the attacker has no apparent influence over the location of uploaded files due to proper input sanitation of paths/filenames, there is no filter for the content or size of the data uploaded.

This endpoint allows remote attackers to perform actions with the permissions of a victim user, provided the victim user has an active session and is induced to trigger the malicious request.
