{"id":"UBUNTU-CVE-2026-107314","details":"pgjdbc, the PostgreSQL JDBC Driver, versions 42.7.11 through 42.7.13 enforce no restriction when the requireAuth connection property excludes all six authentication methods the driver knows, for example requireAuth=!password,!md5,!gss,!sspi,!scram-sha-256,!none. The driver then accepts any method the server asks for, including cleartext password authentication. A value without a method in it, such as requireAuth=, (a single comma), is affected the same way. An attacker positioned between the application and its server can ask for cleartext password authentication and receive the database password. A positive list such as requireAuth=scram-sha-256, and a partial exclusion such as requireAuth=!password,!md5, are enforced correctly. The property has no default value, so a deployment that does not set it is not affected. 42.7.14 fixes the problem: such a connection is refused with SQLState 08004, and a value without a method in it is rejected as invalid.","modified":"2026-10-08T19:47:06.395449477Z","published":"2026-10-08T00:00:00Z","upstream":["CVE-2026-107314"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-107314"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-107314"},{"type":"REPORT","url":"https://github.com/pgjdbc/pgjdbc/security/advisories/GHSA-rhp9-mr79-r74h"},{"type":"REPORT","url":"https://github.com/pgjdbc/pgjdbc/commit/a65ef98fe37bf0ecbd1a6331205cdb924985ed75"}],"affected":[{"package":{"name":"libpgjava","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.2-1002-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpg-java","binary_version":"9.2-1002-1"},{"binary_name":"libpostgresql-jdbc-java","binary_version":"9.2-1002-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107314.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.2-1002-1"],"ecosystem_specific":{"binaries":[{"binary_version":"9.2-1002-1","binary_name":"libpg-java"},{"binary_name":"libpostgresql-jdbc-java","binary_version":"9.2-1002-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107314.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.4.1212-1","9.4.1212-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpostgresql-jdbc-java","binary_version":"9.4.1212-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107314.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["42.2.6-1","42.2.8-1","42.2.9-1","42.2.10-1","42.2.10-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpostgresql-jdbc-java","binary_version":"42.2.10-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107314.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["42.2.23-1","42.2.24-1","42.3.1-1","42.3.2-1","42.3.3-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpostgresql-jdbc-java","binary_version":"42.3.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107314.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["42.5.4-1","42.6.0-2","42.7.0-1","42.7.1-1","42.7.2-1"],"ecosystem_specific":{"binaries":[{"binary_version":"42.7.2-1","binary_name":"libpostgresql-jdbc-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107314.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["42.7.7-1","42.7.8-1","42.7.8-2","42.7.9-1","42.7.10-1"],"ecosystem_specific":{"binaries":[{"binary_version":"42.7.10-1","binary_name":"libpostgresql-jdbc-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107314.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:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
