Prior to 4.81.0, Fleet contained multiple unauthenticated HTTP endpoints that read request bodies without enforcing a size limit. An unauthenticated attacker could exploit this behavior by sending large or repeated HTTP payloads, causing excessive memory allocation and resulting in a denial-of-service (DoS) condition. Version 4.81.0 patches the issue.","state":0,"publishedAt":"2026-03-27T18:23:49.791+00:00","modifiedAt":"2026-03-31T13:38:29.843+00:00","affected":[{"ecosystem":"Vendor product","name":"fleet","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"fleetdm\",\n                    \"product\": \"fleet\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.81.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/fleetdm/fleet/security/advisories/GHSA-99hj-44vg-hfcp"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-26061","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-26061","identifiers":["CVE-2026-26061"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
