{"id":"JLSEC-2026-742","summary":"Partial-chain certificate verification may accept chains that terminate at a peer-supplied,...","details":"Partial-chain certificate verification may accept chains that terminate at a peer-supplied, untrusted intermediate certificate rather than a trusted anchor. An attacker could present a chain that ends at an intermediate they control and have it accepted as valid. This affects the OpenSSL compatibility certificate-path-building path (wolfSSL_X509_verify_cert / X509_STORE, OPENSSL_EXTRA) when the X509_V_FLAG_PARTIAL_CHAIN verify flag is enabled.","modified":"2026-07-18T00:02:22.114741197Z","published":"2026-07-14T21:41:35.775Z","upstream":["CVE-2026-6091","GHSA-mhq8-94h7-mrgx","EUVD-2026-39486"],"database_specific":{"sources":[{"database_specific":{"status":"Analyzed"},"id":"CVE-2026-6091","imported":"2026-07-17T22:34:34.392Z","modified":"2026-06-26T16:50:56.503Z","published":"2026-06-25T18:16:41.447Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-6091","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6091"},{"modified":"2026-06-26T18:34:51Z","published":"2026-06-25T18:30:41Z","url":"https://api.github.com/advisories/GHSA-mhq8-94h7-mrgx","html_url":"https://github.com/advisories/GHSA-mhq8-94h7-mrgx","id":"GHSA-mhq8-94h7-mrgx","imported":"2026-07-17T22:34:34.563Z"},{"id":"EUVD-2026-39486","imported":"2026-07-17T22:34:44.453Z","modified":"2026-06-25T17:58:31Z","published":"2026-06-25T16:46:12Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-39486","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-39486"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-mhq8-94h7-mrgx"},{"type":"WEB","url":"https://github.com/wolfSSL/wolfssl/pull/10170"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6091"},{"type":"WEB","url":"https://www.wolfssl.com/docs/security-vulnerabilities"},{"type":"WEB","url":"https://www.wolfssl.com/docs/security-vulnerabilities/"}],"affected":[{"package":{"name":"wolfSSL_jll","ecosystem":"Julia","purl":"pkg:julia/wolfSSL_jll?uuid=98c43586-9870-5ae5-ab22-acc77b9bbdb5"},"ranges":[{"type":"SEMVER","events":[{"introduced":"5.8.4+0"},{"fixed":"5.9.2+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-742.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
