{"id":"CVE-2026-107314","summary":"pgjdbc does not enforce requireAuth when the value excludes every authentication method","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.","aliases":["GHSA-rhp9-mr79-r74h"],"modified":"2026-10-09T02:49:21.514101844Z","published":"2026-10-07T23:03:01.500Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107314.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"42.7.11"},{"fixed":"42.7.14"}]}],"cna_assigner":"PostgreSQL","cwe_ids":["CWE-636"]},"references":[{"type":"WEB","url":"https://repo.maven.apache.org/maven2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107314.json"},{"type":"ADVISORY","url":"https://github.com/pgjdbc/pgjdbc/security/advisories/GHSA-rhp9-mr79-r74h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107314"},{"type":"PACKAGE","url":"https://github.com/pgjdbc/pgjdbc"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pgjdbc/pgjdbc","events":[{"introduced":"78e261ff2a7f16a37bdceb2204f67e484387da2f"},{"fixed":"3297557c6a8059d0d6e3522c79f0bd9a6f82ee07"}],"database_specific":{"extracted_events":[{"introduced":"42.7.11"},{"fixed":"42.7.13"}],"source":"DESCRIPTION"}}],"versions":["REL42.7.11"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/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"}]}
