{"id":"CVE-2026-107314","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-107314","generatedAt":"2026-10-28T03:39:46.856Z","title":"An attacker positioned between the application and its server can ask for cleartext password authentication and receive the database password.","description":"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.","published":"2026-10-07T23:17:00.000Z","lastModified":"2026-10-08T20:49:23.000Z","status":"Awaiting Analysis","sourceIdentifier":"f86ef6dc-4d3a-42ad-8f28-e6d5547a5007","cvss":{"version":"3.1","score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-636"],"affected":[],"epss":{"score":0.00345,"percentile":0.27914,"date":"2026-10-27","history":[{"date":"2026-10-08","score":0.00256,"percentile":0.1579}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.34%).
