The vulnerability stems from insufficient access control mechanisms within the software's API endpoints for managing dataset prompts and their variations. Specifically, the software fails to validate whether the user attempting to create, update, delete, or retrieve a dataset prompt or its variations has the appropriate organizational permissions. By manipulating the request parameters, such as removing the projectId value, an attacker can bypass the intended access controls. This flaw exposes datasets to unauthorized modifications, potentially compromising data integrity and confidentiality across different organizations.

An attacker, logged in as a user from Organization B, intercepts a request intended to modify a dataset prompt belonging to Organization A. By removing the projectId parameter from the request or manipulating the prompt variation ID, the attacker can successfully execute the request, altering the dataset prompt without authorization. This unauthorized access can lead to data corruption, unauthorized data exposure, or loss of data integrity within the victim organization's datasets.

Organizations using the affected version of the software are at risk. Specifically, datasets owned by these organizations can be manipulated by unauthorized users from other organizations, leading to potential data integrity, confidentiality, and availability issues.
