Name of the Vulnerable Software and Affected Versions Misskey versions prior to 2024.5.0

Description Misskey is an open source, decentralized microblogging platform. The platform does not perform proper normalization on the JSON structures of incoming signed ActivityPub activity objects before processing them. This allows threat actors to spoof the contents of signed activities and impersonate the authors of the original activities.

Recommendations For versions prior to 2024.5.0, update to version 2024.5.0 to fix the vulnerability. As a temporary workaround, consider restricting the processing of incoming signed ActivityPub activity objects until the update is applied.
