Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 3.18% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Red Hat Red Hat build of Keycloak 26.4 and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Cross-source reconciliation

Remediation availability differs by product scope

Verified remediation exists for at least one product or source, but 4 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

1 known affected

The vendor explicitly identifies these products as affected by this CVE.

  • ABB dynovaPRO™ cloud system < 2026-08-27 12:00 (CEST)
Summary
A flaw was found in the reset-credentials flow of the keycloak-services component, which is the core engine for identity and access management in Keycloak. 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.
Remediation
The problem is corrected in the dynovaPRO™ cloud system since 2026-08-27 12:00 (CEST). Users who have received a password reset mail without their consent should reset their password to ensure an attacker did not gain access to their account.

What, why and how

A flaw was found in the reset-credentials flow of the keycloak-services component, which is the core engine for identity and access management in Red Hat Build of Keycloak. 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.

What

A flaw was found in the reset-credentials flow of the keycloak-services component, which is the core engine for identity and access management in Red Hat Build of Keycloak. 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.

Why

The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

NCSC-NL · Dutch · NCSC-2026-0346Kwetsbaarheden verholpen in Siemens producten

Keycloak versions prior to 26.7.2 contain a critical reset-credentials vulnerability in the keycloak-services component that allows unauthenticated attackers to bypass email verification and reset any user's password, potentially gaining full account control.

Official advisory ↗
NCSC-NL · Dutch · NCSC-2026-0326Kwetsbaarheden verholpen in Keycloak

De kwetsbaarheid met CVE-2026-18963 kan een ongeauthenticeerde externe aanvaller in staat stellen om elke gebruikersaccount over te nemen door een wachtwoordreset af te dwingen. Door deze kwetsbaarheid valt het e-mailverificatieproces bij wachtwoordreset te omzeilen en wachtwoorden van gebruikers te wijzigen. In Keycloak zijn daarnaast kwetsbaarheden aanwezig in de Fine-Grained Admin Permissions (FGAP) v2, waardoor bepaalde beheerders met beperkte permissies metadata van verborgen groepen kunnen inzien en details van ongeautoriseerde oudergroepen kunnen blootstellen. Verder kunnen geauthenticeerde aanvallers via een legacy client-initiated account-linking endpoint CSRF-bescherming omzeilen en accounts overnemen. Ook kunnen gedelegeerde beheerders met alleen leesrechten client secrets uitlezen door een fout in de secret rotation. Voor OpenTelemetry Java was er een kwetsbaarheid waarbij het ontbreken van limieten op baggage headers leidde tot onbegrensd geheugen- en CPU-gebruik, wat Denial-of-Service kan veroorzaken. Bij Jackson-libraries is een bypass van de @JsonIgnore annotatie in Java Records vastgesteld, waardoor ongewenste toewijzing aan constructorparameters mogelijk is. Ook zijn er bypasses van @JsonIgnoreProperties, ontbrekende view guards op @JsonUnwrapped en ongeautoriseerde schrijfacties op velden met @JsonView. Oracle Database Server's Fleet Patching and Provisioning component is eveneens getroffen door een kwetsbaarheid die ongeautoriseerde data toegang of Denial-of-Service kan veroorzaken.
