Federated Timeline


Veronica Explains@veronica@explains.social (2026-05-21 22:58:55) I genuinely believe that the Fediverse offers the best chance of recapturing the friendly, optimistic Internet I loved as a kid.

We've got flaws, sure. I've been critical of aspects of fedi culture, and will continue to do so.

But this place represents hope, and hope is where we start.

BotKit by Fedify :botkit:@botkit@hollo.social (2026-05-21 22:20:24) BotKit security updates: 0.3.3 and 0.4.2
If you use BotKit, update to a patched release now. CVE-2026-42462 affects Fedify's Linked Data Signature handling, and BotKit inherits the exposure through its dependency on Fedify.

The vulnerability allows an attacker to use JSON-LD graph-restructuring features—specifically @graph, @included, and @reverse—to reshape a signed ActivityPub activity without invalidating its Linked Data Signature. This can cause BotKit (via Fedify) to interpret a different ActivityPub object shape than was originally signed. The fix normalizes Linked Data Signature-verified activities against Fedify's local JSON-LD context before interpreting them, and rejects the JSON-LD constructs that enable the attack.

All versions of BotKit up to 0.3.2 (in the 0.3.x branch) and 0.4.1 (in the 0.4.x branch) are affected. Patched releases are 0.3.3 and 0.4.2.

For BotKit 0.4.x, update @fedify/botkit:


npm update @fedify/botkit
yarn upgrade @fedify/botkit
pnpm update @fedify/botkit
bun update @fedify/botkit
deno update @fedify/botkit
For BotKit 0.3.x, update @fedify/botkit:


npm update @fedify/botkit@0.3.3
yarn upgrade @fedify/botkit@0.3.3
pnpm update @fedify/botkit@0.3.3
bun update @fedify/botkit@0.3.3
deno update @fedify/botkit@0.3.3
If you use other BotKit-related packages (e.g., @fedify/botkit-postgres), update them as well. After updating, redeploy.

The CVE ID is CVE-2026-42462. See also fedify-dev/fedify#773 for Fedify's own announcement.

Thanks to @Claire for the report and responsible disclosure.

If anything is unclear, feel free to ask on GitHub Discussions or Matrix.

Reply to @stefano@mastodon.bsd.cafe The Real Grunfink@grunfink@comam.es (2026-05-21 21:00:31) If what 'split domains' mean is "running #snac in subdomain.example.com but identify as accounts from example.com" then no, it's not supported.

But, you can have snac running from a subdirectory of your main domain (which, as far as I know, no other fediverse implementation does). I.e. you can have your snac root in example.com/social and then you can identify as you@example.com . So you have no unnecessary subdomain just to be you.

Which is what I do for this very domain.

Dale Hitchenor@dhitchenor@fe.disroot.org (2026-05-21 19:59:24) Hello all,

My apologies for my tardiness; life does get in the way sometimes.

On a good note, Hubzilla was updated to 11.2.1 about a day ago, and the docker image is about an hour or so away from being released. I want to personally thank you for your patience; the runners are busy crunching the code, and building as we speak.

Special thanks goes out to the Hubzilla devs, and contributors for their fine work. If you are curious, you can find their work at:
https://framagit.org/hubzilla/core

The release is available for review at:
https://framagit.org/hubzilla/core/-/releases

And of course, when it drops, the docker image will be available at:
https://hub.docker.com/r/dhitchenor/hubzilla

I hope this finds you all well; please stay safe, and I'll see you on the fediverse.

Todd Sundsted@toddsundsted@epiktistes.com (2026-05-21 19:50:48) Release v3.3.9 of Ktistec continues the security hardening work from recent releases, with further progress on the Mastodon-compatible API.

Of note: all network connections now go through a new Ktistec::Network module. This allows Ktistec to limit the size of HTTP bodies it reads, on both inbound and outbound requests, and ensures it only opens connections to valid remote IP addresses.

Here's the full changelog:

Added

New Mastodon-compatible APIs.
Fixed

Close DNS rebinding window for outbound HTTP requests.
Limit the size of HTTP bodies the server reads.
Sanitize RSS feed output to prevent CDATA breakout.
Destroy all sessions and access tokens on account termination.
Changed

Ensure all GET and POST requests utilize Ktistec::Network.
Process local recipients in-process in inbox/outbox activity processors.
As always, it's worth upgrading for the security fixes!

俺は無駄な希望的観測をしたい

xz@xz@ebadf.port0.org (2026-05-21 18:09:00) One annoyance with my small #snac instance - or any small Fediverse island regardless of the software - is the missing visibility of the rest of the network. For followed hashtags, I am missing out on most posts as I am not federating with most instances.

The usual solution is to use an ActivityPub relay. This, however, resulted in receiving looots of posts, hitting file size and inode limits on this small VM. Thus, I gave up this experiment a while ago.

Now, I just stumbled about https://relay.fedi.buzz/ from @astro@c3d2.social, which allows to only follow certain hashtags, which is kinda exactly what I wanted ❤️

After following the Subscribing to Fediverse Relays section from snac(8), I came up with the following jq(1) command to subscribe each hashtag I am already following on my #snac instance. And yes, this would be way faster to do by hand for those six hashtags in total.

$ # Create multiple snac follow commands for each hashtag the "xz"
$ # user follows. The "data" directory is the $SNAC_BASEDIR.
$ jq -j \
'.followed_hashtags.[] | "snac follow data relay https://relay.fedi.buzz/tag/",.[1:],"; "' \
< data/user/xz/user.json
snac follow data relay https://relay.fedi.buzz/tag/openbsd; snac follow data relay https://relay.fedi.buzz/tag/snac; [ . . . ]

If the generated commands are looking not suspicious enough, rerun the command within $() or execute the output manually.

Finally, I am able to doomscroll #biketooter for weird and ridiculously expensive bikes from my instance; yay!
