In 3.0.12, a peer offering only Digest qop=auth-int causes mutual-authentication verification to be skipped. AuthenticatorUtils.computeExpectedRspAuth returns no expected value for auth-int, and Interceptors treats that result as unverifiable but nonfatal, so a response with an invalid rspauth value is accepted. A peer that does not know the shared secret can therefore be accepted as the authenticated server. This issue is fixed in version 3.0.13.","state":0,"publishedAt":"2026-10-07T21:10:26.049+00:00","modifiedAt":"2026-10-08T15:02:48.131+00:00","affected":[{"ecosystem":"Vendor product","name":"async-http-client","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"AsyncHttpClient\",\n                    \"product\": \"async-http-client\",\n                    \"versions\": [\n                        {\n                            \"version\": \"= 3.0.12\",\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:L/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.8,"severity":"HIGH"}],"references":["https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-qhv6-3pmh-95q4","https://github.com/AsyncHttpClient/async-http-client/commit/a5422493b638226666a1ecb5f82826c7c7845b99","https://github.com/AsyncHttpClient/async-http-client/releases/tag/async-http-client-project-3.0.13"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107279","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107279","identifiers":["CVE-2026-107279"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
