Introducing . Hollo is an -enabled single-user microblogging software. Although it's for a single user, it also supports creating and running multiple accounts for different topics.

It's headless, meaning you can use existing client apps instead, with its Mastodon-compatible APIs. It has most feature parity with Mastodon. Two big differences with Mastodon is that you can use in the content of your posts and you can quote another post.

Oh, and Hollo is built using and .

Okay, since we couldn't get in touch with the @fedify account owner, we need a new name for our GitHub organization. Which alternative do you prefer?

Your suggestions for other names are welcome in the comments! We'll make the final decision based on your feedback.

@fedify@hollo.social

We're planning to move our GitHub repository to an organization account for better project management. We've requested GitHub support to help us acquire the inactive @fedify username for this purpose. (The attached screenshot is our formal request to GitHub support.)

If we successfully acquire @fedify, that will be our new organization name. If not, we'll choose an alternative name. We'll keep you updated on the progress!

In any case, we'll ensure a smooth transition with proper redirects from the current repository. Stay tuned for updates!

Dear GitHub Support,

I am writing to request the takeover of the inactive GitHub username “@fedify”. This username is currently held by an account that shows no activity since its creation—no repositories, contributions, or any other engagement.

I am the maintainer of the Fedify project (https://github.com/dahlia/fedify), which is an open source ActivityPub server framework. We would like to use this username as an organization account to host our project and related repositories.

The reasons for this request are:

1. The current “@fedify” account has been completely inactive with no public contributions or repositories
2. The name directly relates to our project's name and purpose
3. We need an organization account to better manage our growing open source project
4. The username would help us maintain consistent branding across different platforms (@fedify on npm, JSR, etc.)

If possible, we would greatly appreciate if you could help us acquire this username. We believe this would benefit the GitHub community by putting the inactive username to active use for an open source project.

Please let me know if you need any additional information to process this request.

Thank you for your time and consideration.

Best regards,
Hong Minhee (@dahlia)

프레임워크의 구현에서 발견된 보안 취약점 CVE-2025-23221을 해결하기 위한 보안 업데이트(1.0.14, 1.1.11, 1.2.11, 1.3.4)를 배포했습니다. 모든 사용자께서는 각자 사용 중인 버전에 해당하는 최신 버전으로 즉시 업데이트하시기를 권장합니다.

취약점 내용

보안 연구자가 Fedify의 lookupWebFinger() 함수에서 다음과 같은 보안 문제점들을 발견했습니다:

  • 무한 리다이렉트 루프를 통한 서비스 거부 공격 가능
  • 내부 네트워크 주소로의 리다이렉트를 통한 SSRF (서버측 요청 위조) 공격 가능
  • 리다이렉트 조작을 통한 의도하지 않은 URL 스킴 접근 가능

수정된 버전

  • 1.3.x 시리즈: 1.3.4로 업데이트
  • 1.2.x 시리즈: 1.2.11로 업데이트

  2. 원래 요청과 동일한 스킴(HTTP/HTTPS)으로만 리다이렉트 허용하도록 제한
  3. SSRF 공격 방지를 위해 내부 네트워크 주소로의 리다이렉트 차단

업데이트 방법

다음 명령어로 최신 보안 버전으로 업데이트하실 수 있습니다:

# npm 사용자의 경우
npm update @fedify/fedify

# Deno 사용자의 경우
deno add jsr:@fedify/fedify

이 취약점을 책임감 있게 보고해 주신 보안 연구자께 감사드립니다. 덕분에 신속하게 문제를 해결할 수 있었습니다.

We have released updates (1.0.14, 1.1.11, 1.2.11, 1.3.4) to address CVE-2025-23221, a in 's implementation. We recommend all users update to the latest version of their respective release series immediately.

The Vulnerability

A security researcher identified multiple security issues in Fedify's lookupWebFinger() function that could be exploited to:

  • Perform denial of service attacks through infinite redirect loops
  • Execute server-side request forgery () attacks via redirects to private network addresses
  • Access unintended URL schemes through redirect manipulation

Fixed Versions

  • 1.3.x series: Update to 1.3.4
  • 1.2.x series: Update to 1.2.11
  • 1.1.x series: Update to 1.1.11
  • 1.0.x series: Update to 1.0.14

Changes

The security updates implement the following fixes:

  1. Added a maximum redirect limit (5) to prevent infinite redirect loops
  2. Restricted redirects to only follow the same scheme as the original request (HTTP/HTTPS)
  3. Blocked redirects to private network addresses to prevent SSRF attacks

How to Update

To update to the latest secure version:

# For npm users
npm update @fedify/fedify

# For Deno users
deno add jsr:@fedify/fedify

We thank the security researcher who responsibly disclosed this vulnerability, allowing us to address these issues promptly.
