SCA: security update for misskey-js (GHSA-wwrj-3hvj-prpm)

medium Tenable Self-Hosted Container Security Plugin ID 436391

Description

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

 - Misskey is an open source, federated social media platform. Attackers who use an untrusted reverse proxy
 or not using a reverse proxy at all can bypass IP rate limiting by adding a forged X-Forwarded-For header.
 Starting with version 2025.9.1, an option (`trustProxy`) has been added in config file to prevent this
 from happening. However, it is initialized with an insecure default value before version
 2025.12.0-alpha.2, making it still vulnerable if the configuration is not set correctly. This is patched
 in v2025.12.0-alpha.2 by flipping default value of `trustProxy` to `false`. Users of a trusted reverse
 proxy who are unsure if they manually overode this value should check their config for optimal behavior.
 Users are running Misskey with a trusted reverse proxy should not be affected by this vulnerability. From
 v2025.9.1 to v2025.11.1, workaround is available. Set `trustProxy: false` in config file. (CVE-2025-66482)
