VCID-wpep-ax9c-jyb6 Aliases: CVE-2026-42462 GHSA-9rfg-v8g9-9367	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.	2.0.18 Affected by 0 other vulnerabilities. 2.1.14 Affected by 0 other vulnerabilities. 2.2.3 Affected by 0 other vulnerabilities.
VCID-yfms-12uu-a7hy Aliases: CVE-2026-34148 GHSA-gm9m-gwc4-hwgp	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.	2.0.8 Affected by 0 other vulnerabilities. 2.1.1 Affected by 0 other vulnerabilities.
