Details
Summary
CVE-2024-25636 is a vulnerability in Misskey, an open source social media platform with ActivityPub support. Versions prior to 2024.2.0 do not check the `Content-Type` header value when fetching remote Activity Streams objects, allowing a threat actor to upload a crafted Activity Streams document to a remote server. If the server accepts arbitrary user uploads and serves them in response to requests with an `Accept` header value of the Activity Streams media type, the threat actor can impersonate and take over an account on that server. The vulnerability poses a high risk to organizations as it allows unauthorized access and control over accounts. The issue has been patched in version 2024.2.0, providing remediation for the vulnerability.
