The UpStream plugin, which is used for project management on WordPress, has a security issue that allows unauthorized access. This is because a certain function in all versions, up to 2.1.0, does not have a check to ensure only authorized users can use it. This means that anyone with Subscriber-level access or higher can perform actions without permission.
