your_spotify is an open source, self hosted Spotify tracking dashboard. YourSpotify version < 1.9.0 does not prevent other pages from displaying it in an iframe and is thus vulnerable to clickjacking. Clickjacking can be used to trick an existing user of YourSpotify to trigger actions, such as allowing signup of other users or deleting the current user account. Clickjacking works by opening the target application in an invisible iframe on an attacker-controlled site and luring a victim to visit the attacker page and interacting with it. By positioning elements over the invisible iframe, a victim can be tricked into triggering malicious or destructive actions in the invisible iframe, while they think they interact with a totally different site altogether. When a victim visits an attacker-controlled site while they are logged into YourSpotify, they can be tricked into performing actions on their YourSpotify instance without their knowledge. These actions include allowing signup of other users or deleting the current user account, resulting in a high impact to the integrity of YourSpotify. This issue has been addressed in version 1.9.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.
The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain, which can lead to user confusion about which interface the user is interacting with.
