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
 versions 1.9.11, 1.10.10, 2.0.18, 2.1.14, and 2.2.3, an attacker can make use of JSON-LD features to
 restructure a JSON-LD document that would change how Fedify interprets it without changing its Linked Data
 Signature, allowing them to alter a third-party signed activity they have received. Versions 1.9.11,
 1.10.10, 2.0.18, 2.1.14, and 2.2.3 fix the issue. (CVE-2026-42462)
