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.","state":0,"publishedAt":"2026-04-06T16:16:34.387+00:00","modifiedAt":"2026-06-17T10:38:34.75+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/fedify-dev/fedify/releases/tag/1.10.5","https://github.com/fedify-dev/fedify/releases/tag/1.9.6","https://github.com/fedify-dev/fedify/releases/tag/2.0.8","https://github.com/fedify-dev/fedify/releases/tag/2.1.1","https://github.com/fedify-dev/fedify/security/advisories/GHSA-gm9m-gwc4-hwgp"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-34148","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-400","CWE-770"],"productCriteria":["cpe:2.3:a:fedify:fedify\\/fedify:*:*:*:*:*:node.js:*:*","cpe:2.3:a:fedify:fedify\\/vocab-runtime:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-04-06T16:16:34.387","lastModified":"2026-06-17T10:38:34.750"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
