The issue occurs because the system fails to verify if an authenticator is valid for the current authentication flow when switching between the standard authentication path and the reset credentials path. An authenticated attacker can exploit this by triggering a race condition during the credential reset process to associate their successful authentication state with another user's session. This can result in the attacker gaining full access to the victim's account and changing their password.","epss":{"date":"2026-11-06","percentile":0.21917,"score":0.00292},"exploits":[],"kev":null,"metrics":[{"score":7.5,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},{"score":7.5,"severity":"high","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793994912581,"publishedAt":1793894687843,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95759"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95760"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95761"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95762"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-103112"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95759"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95760"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95761"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95762"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/security/cve/CVE-2026-103112"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"--- CME Mitigation Guidance (2026-11-06) ---\nDisclaimer: The following mitigation solutions are provided as a courtesy, pending the application of an official patch.

Until patched, this is a concern on Keycloak deployments with Forgot Credentials enabled and users without two-factor authentication, so Enforce two-factor authentication for all realm users or disable the Forgot Credentials feature to prevent cross-flow identity binding. These controls limit blast radius and contain exploitation, but they do not fix the underlying authentication race condition defect — apply the upstream patch to fully remediate.\n\nHighest-impact CME: CME-801 Multi-Factor Authentication (MFA) (high)"}],"revision":"281c598fa42ece9ae5911e067716cd3e37ecdcd2b3de7b35f219d786ffc926f2","sources":[{"modifiedAt":1793994912581,"name":"CNA: redhat","retrievedAt":1793995734349,"url":"https://www.cve.org/CVERecord?id=CVE-2026-103112"},{"modifiedAt":1793985430563,"name":"NVD","retrievedAt":1793990087620,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-103112"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793988621992,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-103112"}],"ssvc":null,"status":"published","title":"Keycloak-services: keycloak-services: account takeover via authentication race using reset-credentials path","updatedAt":1793995734349}
