Marielle | Nova(๐ Marielle) Reminder for fedi admins who may have missed the memo: The Mastodon (and forks), Misskey (and forks), IceShrimp, Wafrn, Fedify, and Hollo development teams issued critical security releases for their software between 2026-05-20 and 2026-05-22.
I have gathared releases for well-known software and forks and put them in the post this one is quoting. If you cannot find your software, please check its repository; if no release exists, please check with the development team of your software if your software is vulnerable, and if it is, please ask if you need to your instance down until it can be patched. The vulnerability in question affects ActivityPub software that supports Linked-Data Signatures, and vulnerable instances are urged to shut down until they and their software can be patched.
