    Artifact disclosure to a mentioned user via email notifications

    When users are mentioned in the comments of an artifact, they receive an email notification even if they do not have the necessary permissions to access the artifact. The notification sent may contain the entire content of the artifact if field permissions allow it.

    Impact

    Users may potentially access confidential information from artifacts that they are not authorized to view.

    CVSSv3.1 score: 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)

    Exploitation

    1. Create an artifact in a tracker where access is restricted to certain users.
    2. Comment something in this artifact and mentioning one of the users who does not have access rights.
    3. Open the mailbox associated with this user's account.
