    Title
    Fedify has an Infinite loop and Blind SSRF found inside the Webfinger mechanism
    Summary
    Fedify is a TypeScript library for building federated server apps powered by ActivityPub and other standards. This vulnerability allows a user to maneuver the Webfinger mechanism to perform a GET request to any internal resource on any Host, Port, URL combination regardless of present security mechanisms, and forcing the victim’s server into an infinite loop causing Denial of Service. Moreover, this issue can also be maneuvered into performing a Blind SSRF attack. This vulnerability is fixed in 1.0.14, 1.1.11, 1.2.11, and 1.3.4.

    CVE-2024-39687 (GCVE-0-2024-39687)

    Title
    Fedify vulnerable to allowing access to internal network resources
    Summary
    Fedify is a TypeScript library for building federated server apps powered by ActivityPub and other standards. At present, when Fedify needs to retrieve an object or activity from a remote activitypub server, it makes a HTTP request to the `@id` or other resources present within the activity it has received from the web. This activity could reference an `@id` that points to an internal IP address, allowing an attacker to send request to resources internal to the fedify server's network. This applies to not just resolution of documents containing activities or objects, but also to media URLs as well. Specifically this is a Server Side Request Forgery attack. Users should upgrade to Fedify version 0.9.2, 0.10.1, or 0.11.1 to receive a patch for this issue.
