CVE-2025-46553

LOW2.1

@misskey-dev/summaly Redirect Filter Bypass

Published May 5, 2025

Modified 8 months ago

No fix available

Details

@misskey-dev/summaly is a tool for getting a summary of a web page. Starting in version 3.0.1 and prior to version 5.2.1, a logic error in the main summaly function causes the allowRedirects option to never be passed to any plugins, and as a result, isn't enforced. Misskey will follow redirects, despite explicitly requesting not to. Version 5.2.1 contains a patch for the issue.
