**Name of the Vulnerable Software and Affected Versions** Misskey versions prior to 2023.11.1-beta.1 **Description** Misskey is an open source, decentralized social media platform. The issue allows arbitrary users to impersonate any remote user due to missing signature validation. **Recommendations** For versions prior to 2023.11.1-beta.1, update to version 2023.11.1-beta.1 to resolve the issue. As a temporary workaround, consider restricting access to remote user impersonation functionality until the patch is applied.
