The issue allows an unauthenticated attacker to force the password reset process for any user without needing to click the required email verification link. This can result in the attacker gaining full control over target user accounts by directly setting new credentials.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1},"cwes":["CWE-640"],"references":["https://access.redhat.com/errata/RHSA-2026:56519","https://access.redhat.com/errata/RHSA-2026:56520","https://access.redhat.com/errata/RHSA-2026:56523","https://access.redhat.com/errata/RHSA-2026:56524","https://access.redhat.com/security/cve/CVE-2026-18963"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:35.584907681+00:00"},"epss":{"cve":"CVE-2026-18963","score":0.04682,"percentile":0.91715,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-4gv3-mc9p-5wqc","url":"https://osv.dev/vulnerability/GHSA-4gv3-mc9p-5wqc","summary":"Keycloak: Unauthenticated account takeover via reset-credentials flow bypass","modified":"2026-08-28T23:10:21.393396262Z","packages":[{"ecosystem":"Maven","name":"org.keycloak:keycloak-services","purl":"pkg:maven/org.keycloak/keycloak-services","ranges":[">=26.0.0 <26.4.15"],"fixed":["26.4.15"]},{"ecosystem":"Maven","name":"org.keycloak:keycloak-services","purl":"pkg:maven/org.keycloak/keycloak-services","ranges":[">=26.5.0 <26.6.6"],"fixed":["26.6.6"]},{"ecosystem":"Maven","name":"org.keycloak:keycloak-services","purl":"pkg:maven/org.keycloak/keycloak-services","ranges":[">=26.7.0 <26.7.2"],"fixed":["26.7.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
