CVE-2025-46559
May 05, 2025
Misskey is an open source, federated social media platform. Starting in version 12.31.0 and prior to version 2025.4.1, missing validation in "Mk:api" allows malicious AiScript code to access additional endpoints that it isn't designed to have access to. The missing validation allows malicious AiScript code to prefix a URL with "../" to step out of the "/api" directory, thereby being able to make requests to other endpoints, such as "/files", "/url", and "/proxy". Version 2025.4.1 fixes the issue.
