On Windows, SSPI used the service account's logon in the same way. psql was also started with pgAdmin's environment, which could hold another user's credential cache while that user was connecting.\n\nThe fix points KRB5CCNAME and KRB5_CLIENT_KTNAME at a file that cannot exist except while a Kerberos-authenticated user connects with Kerberos, and gives every other connection, psql and the utilities require_auth=!gss,!sspi and gssencmode=disable, checked on the final connection string. require_auth needs libpq 16 or later.\n\nThis issue affects pgAdmin 4: before 9.19.","score":8.2,"severity":"high","published":"2026-10-30T19:55:15.101Z","modified":"2026-10-30T19:55:15.101Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"pgadmin.org","name":"pgAdmin 4","platforms":[],"versions":[{"version":"0","status":"affected","lessThan":"9.19","versionType":"custom"}],"defaultStatus":"unaffected","cpes":[],"source":"PostgreSQL","url":"https://www.cve.org/CVERecord?id=CVE-2026-116244"}],"remediation":[],"references":["https://github.com/pgadmin-org/pgadmin4/issues/10655","https://github.com/pgadmin-org/pgadmin4/commit/145e511f05eed69ebcadd3cd61ffea0a5b4c69a4"],"sources":[{"name":"CVE","id":"CVE-2026-116244","modified":"2026-10-30T19:55:15.101Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-116244"}],"assessments":[{"source":"PostgreSQL","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N","score":8.2},{"source":"PostgreSQL","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:N","score":7.1}],"sourceAffected":[],"observedAt":"2026-10-30T20:24:38.788Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T09:10:30.844Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":{"text":"pgAdmin 4, before version 9.19, uses the service account's Kerberos credentials when a connection is not meant to use delegated credentials, allowing any user to connect as the service account's Kerberos principal.
