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":"2026-04-06T15:06:53.197+00:00","modifiedAt":"2026-04-07T14:25:51.368+00:00","affected":[{"ecosystem":"Vendor product","name":"fedify","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"@fedify\",\n                    \"product\": \"fedify\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.9.6\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 1.10.0, < 1.10.5\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.0.0, < 2.0.8\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.1.0, < 2.1.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"vocab-runtime","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"@fedify\",\n                    \"product\": \"vocab-runtime\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.0.8\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.1.0, < 2.1.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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/security/advisories/GHSA-gm9m-gwc4-hwgp","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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-34148","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-34148","identifiers":["CVE-2026-34148"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
