{"id":"CVE-2026-11703","summary":"Missing SNI/ALPN binding on stateful (session-ID) TLS session resumption","details":"Missing SNI/ALPN binding on stateful (session-ID) resumption, which previously skipped the binding check performed for ticket-based resumption. A cached session could be resumed under a different SNI/ALPN than originally negotiated and, where client-authentication policy differs across virtual hosts, carry the cached peer-authentication state into a context it was not established for. Resumption now verifies the SNI/ALPN binding for all paths and declines (falling back to a full handshake) on mismatch.","modified":"2026-07-16T03:48:15.492760727Z","published":"2026-06-25T21:15:20.576Z","database_specific":{"cna_assigner":"wolfSSL","cwe_ids":["CWE-287"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/11xxx/CVE-2026-11703.json"},"references":[{"type":"WEB","url":"https://www.wolfssl.com/docs/security-vulnerabilities/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/11xxx/CVE-2026-11703.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-11703"},{"type":"FIX","url":"https://github.com/wolfSSL/wolfssl/pull/10489"},{"type":"PACKAGE","url":"https://github.com/wolfSSL/wolfssl"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wolfssl/wolfssl","events":[{"introduced":"b63d3173a1fa2792efda89d0e6706900250131ea"},{"fixed":"ac01707f552c611fbd135cc723b2682b3e7f80f2"}],"database_specific":{"cpe":"cpe:2.3:a:wolfssl:wolfssl:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"3.15.0"},{"last_affected":"5.9.1"},{"fixed":"5.9.2"}],"source":["AFFECTED_FIELD","CPE_RANGE"]}}],"versions":["v5.9.1-stable","v5.9.0-stable","v5.8.4-stable","wolfEntropy2d","v5.8.2-stable","wolfEntropy1","v5.8.0-stable","v5.7.6-stable","v5.7.4-stable","v5.2.1","v5.7.2-stable","v5.7.0-stable","v5.6.6-stable","v5.6.4-stable","WCv5.0-RC12","WCv5.0-RC11","WCv5.0-RC10","v5.6.2-stable","v5.6.3-stable","v5.6.0-stable","v5.5.4-stable","v5.5.3-stable","v5.5.2-stable","v5.5.1-stable","v5.5.0-stable","v5.4.0-stable","v5.3.0-stable","v5.2.0-stable","v5.1.0-stable","v5.0.0-stable","WCv5.0-RC9","v4.8.0-stable","v4.7.1r","v4.7.0-stable","v4.6.0-stable","v4.5.0-stable","v4.4.0-stable","v4.3.0-stable","v4.2.0c","v4.2.0-stable","v4.1.0-stable","v4.0.0-stable","list","v3.15.7-stable","v3.15.6","v3.15.5a","v3.15.5-stable","WCv4-rng-stable","v3.15.3-stable","l","v3.15.0-stable"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-11703.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
