CVE-2025-46559 (GCVE-0-2025-46559)

Vulnerability from cvelistv5 – Published: 2025-05-05 18:38 – Updated: 2025-05-05 18:44
VLAI?
Summary
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.
Severity ?
