SCA: security update for webfinger.js (GHSA-8xq3-w9fx-74rv)

medium Tenable Self-Hosted Container Security Plugin ID 428677

Description

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

- webfinger.js is a TypeScript-based WebFinger client that runs in both browsers and Node.js environments.
In versions 2.8.0 and below, the lookup function accepts user addresses for account checking. However, the
ActivityPub specification requires preventing access to localhost services in production. This library
does not prevent localhost access, only checking for hosts that start with "localhost" and end with a
port. Users can exploit this by creating servers that send GET requests with controlled host, path, and
port parameters to query services on the instance's host or local network, enabling blind SSRF attacks.
This is fixed in version 2.8.1. (CVE-2025-54590)
