{"id":"DEBIAN-CVE-2026-78323","details":"A flaw was found in JSS (Java Security Services). The JSSTrustManager class does not verify NSS trust flags when validating CA certificates, allowing certificates present in the NSS database without TRUSTED_CA flags to be accepted as trust anchors for TLS connections. In non-default configurations where certificate revocation checking is disabled, this could allow a man-in-the-middle attacker to forge certificates accepted by PKI client connections.","modified":"2026-09-14T17:03:34.582573496Z","published":"2026-08-24T12:16:56.250Z","upstream":["CVE-2026-78323"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-78323"}],"affected":[{"package":{"name":"jss","ecosystem":"Debian:12","purl":"pkg:deb/debian/jss?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.3.0-1","5.4.0-1","5.4.2-1","5.5.0-1","5.9.0~beta3-1","5.9.0~beta3-2","5.9.0~beta3-3","5.9.0~beta3-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-78323.json"}},{"package":{"name":"jss","ecosystem":"Debian:14","purl":"pkg:deb/debian/jss?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.1-4","4.3.1-5","4.3.1-6","4.3.1-7","4.4.2-1","4.4.2-2","4.4.2-3","4.4.2-4","4.4.2-5","4.4.2-6","4.4.3-1","4.4.4-1","4.5.0-1","4.5.0~a4-1","4.5.1-1","4.5.3-1","4.5.3-2","4.6.0-1","4.6.1-1","4.6.1-2","4.6.1-3","4.6.2-1","4.6.3-1","4.7.0-1","4.7.0~b1-1","4.7.0~b4-1","4.7.0~b4-2","4.7.1-1","4.7.2-1","4.7.3-1","4.8.0-1","4.8.0-2","4.9.1-1","5.0.0-1","5.1.0-1","5.2.0-1","5.3.0-1","5.4.0-1","5.4.2-1","5.5.0-1","5.9.0~beta3-1","5.9.0~beta3-2","5.9.0~beta3-3","5.9.0~beta3-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-78323.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N"}]}
