CVSS v3.1

9.0

Critical

VectorAV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Misskey versions prior to 2023.12.1
Description Misskey is an open source, decentralized social media platform. Third-party applications may be able to access some endpoints or Websocket APIs that are incorrectly specified without the user's permission and perform operations such as reading or adding non-public content. If the user who authenticated the application is an administrator, confidential information such as object storage secret keys and SMTP server passwords will be leaked, and general users can also create invitation codes without permission and leak non-public user information. Approximately 2,133 instances are mainly distributed in Japan, the United States, and other countries.
Recommendations For versions prior to 2023.12.1, update to version 2023.12.1 to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable endpoints and Websocket APIs until the update is applied. Avoid using third-party applications that may exploit this issue until they are updated to work with the patched version of Misskey.
