{"cve":"CVE-2026-9058","nvd":{"published":"2026-05-25T14:16:27.977","modified":"2026-07-23T12:18:52.540","status":"Deferred","description":"For untrusted certificates that contain the \"Authority Information Access - caIssuers URI\" extension, Szafir SDK will automatically download the parent CA certificate from the specified URL and will import it to its trust store as a \"nonqualified\" certificate. In such a case, Szafir SDK returns a success status code of 0 (\"Positively verified\") upon successful cryptographic verification and a certificate status of \"nonqualified\".\n\nFor other types of untrusted certificates, Szafir SDK returns a success status code of 0 (\"Positively verified\") upon successful cryptographic verification and a certificate status of \"nondetermined\".\n\nThis may lead integrating applications to incorrectly treat the digital signature as valid despite an untrusted certificate chain. This flaw enables authentication bypass and user impersonation:\n(1) in use-cases other than qualified certificate authentication, or\n(2) if the qualified certificate authentication use-case is not correctly implemented by the integrating application.\n\nThis issue was fixed in version 1.8.463.2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":null,"cwes":["CWE-295","CWE-393","CWE-637"],"references":["https://cert.pl/posts/2026/05/CVE-2026-9058","https://www.elektronicznypodpis.pl/"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-9058","score":0.0031,"percentile":0.23847,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
