SCA: security update for @fedify/fedify, @fedify/vocab-runtime (GHSA-gm9m-gwc4-hwgp)

high Tenable Cloud Security Plugin ID 439961

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Fedify is a TypeScript library for building federated server apps powered by ActivityPub. Prior to 1.9.6,
 1.10.5, 2.0.8, and 2.1.1, @fedify/fedify follows HTTP redirects recursively in its remote document loader
 and authenticated document loader without enforcing a maximum redirect count or visited-URL loop
 detection. An attacker who controls a remote ActivityPub key or actor URL can force a server using Fedify
 to make repeated outbound requests from a single inbound request, leading to resource consumption and
 denial of service. This vulnerability is fixed in 1.9.6, 1.10.5, 2.0.8, and 2.1.1. (CVE-2026-34148)

Solution

Update the @fedify/fedify library and its related packages to version 1.10.5 or later.
