{"id":"CVE-2023-4918","aliases":["GHSA-5q66-v53q-pm35"],"url":"https://o3.security/vulnerability/CVE-2023-4918","summary":"Plaintext storage of user password","details":"A flaw was found in the Keycloak package, more specifically org.keycloak.userprofile. When a user registers itself through registration flow, the \"password\" and \"password-confirm\" field from the form will occur as regular user attributes. All users and clients with proper rights and roles are able to read users attributes, allowing a malicious user with minimal access to retrieve the users passwords in clear text, jeopardizing their environment.","published":"2023-09-12T19:24:59.955Z","modified":"2026-08-07T11:31:01.269693032Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.keycloak:keycloak-core","fixedVersion":"22.0.3"}],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2023-4918"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/4xxx/CVE-2023-4918.json"},{"type":"ADVISORY","url":"https://github.com/keycloak/keycloak/security/advisories/GHSA-5q66-v53q-pm35"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-4918"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2238588"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:01.269693032Z"}}
