CVE-2025-24897
Misskey CSRF vulnerability due to insecure configuration of authentication cookie attributes
Description
Misskey is an open source, federated social media platform. Starting in version 12.109.0 and prior to version 2025.2.0-alpha.0, due to a lack of CSRF protection and the lack of proper security attributes in the authentication cookies of Bull's dashboard, some of the APIs of bull-board may be subject to CSRF attacks. There is a risk of this vulnerability being used for attacks with relatively large impact on availability and integrity, such as the ability to add arbitrary jobs. This vulnerability was fixed in 2025.2.0-alpha.0. As a workaround, block all access to the `/queue` directory with a web application firewall (WAF).
