    Allocation of Resources Without Limits or Throttling

    org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

    Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling when caching JWT tokens, which are not limited in their expiration time. An attacker can cause the consumption of excessive memory by sending malicious JWT tokens.

    Incorrect User Management

    org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

    Affected versions of this package are vulnerable to Incorrect User Management in oidc/OrganizationMembershipMapper.java, which relies on matching the domain of a user's email address to map them to an organization. A user can make an unauthorized token claim including association with an organization that they are not actually mapped to. If self-registration is enabled and unrestricted, this is easier to exploit.

    How to fix Incorrect User Management?

    Upgrade org.keycloak:keycloak-services to version 26.1.3 or higher.

    Exposure of Sensitive Information Through Environmental Variables

    org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

    Affected versions of this package are vulnerable to Exposure of Sensitive Information Through Environmental Variables through user-configurable URLs.

    Exploiting this vulnerability is possible with the configuration of backchannel logout URLs or admin URLs, when including placeholders like ${env.VARNAME} or ${PROPNAME}, which are replaced with actual values during URL processing. An attacker can access sensitive server environment variables and system properties.

    How to fix Exposure of Sensitive Information Through Environmental Variables?

    Upgrade org.keycloak:keycloak-services to version 26.0.8 or higher.

    Denial of Service (DoS)

    org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

    Affected versions of this package are vulnerable to Denial of Service (DoS) by modification of security headers and inserting newlines. An attacker can cause the server to process a terminated request, leading to service failure.

    Note: This is only exploitable if the attacker can change realm settings.

    How to fix Denial of Service (DoS)?

    Upgrade org.keycloak:keycloak-services to version 26.0.8 or higher.

    External Control of File Name or Path

    org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

    Affected versions of this package are vulnerable to External Control of File Name or Path. An attacker could read sensitive information from a Vault file that is not within the expected context by exploiting this vulnerability.

    Note:

    This is only exploitable if the attacker has previous high access to the Keycloak server in order to perform resource creation.

    How to fix External Control of File Name or Path?

    Upgrade org.keycloak:keycloak-services to version 26.0.6 or higher.

    Regular Expression Denial of Service (ReDoS)

    org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

    Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) via the SearchQueryUtils method due to improper input sanitization. An attacker could exhaust system resources and achieve denial of service by exploiting this vulnerability.

    HTTP Request Smuggling

    org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

    Affected versions of this package are vulnerable to HTTP Request Smuggling due to improper handling of proxy headers resulting in costly DNS resolution operations. An attacker could tie up IO threads and potentially cause a denial of service by exploiting these operations.

    Notes:

    1. This is only exploitable if the attacker has access to send requests to a Keycloak instance that is configured to accept proxy headers, specifically when reverse proxies do not overwrite incoming headers, and Keycloak is configured to trust these headers.

    2. For versions 26.x, this is only exploitable if the realm must have SslRequired=EXTERNAL (the default), HTTP must be enabled, the instance must not be using a full hostname URL, access must come from behind a proxy (assuming the proxy overwrites the X-Forwarded-For header), and trusted proxies must not be set or must incorrectly trust the client from which the request is originating.

    How to fix HTTP Request Smuggling?

    Upgrade org.keycloak:keycloak-services to version 26.0.6 or higher.

    Open Redirect

    org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

    Affected versions of this package are vulnerable to Open Redirect due to a misconfiguration flaw in the validation of redirect URIs. An attacker can redirect users to an arbitrary URL and potentially expose sensitive information such as authorization codes, leading to session hijacking. Exploiting this vulnerability is possible if a Valid Redirect URI is set to http://localhost/ or http://127.0.0.1/.

    How to fix Open Redirect?

    Upgrade org.keycloak:keycloak-services to version 22.0.13, 24.0.8, 25.0.6 or higher.

    URL Redirection to Untrusted Site ('Open Redirect')

    org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

    Affected versions of this package are vulnerable to URL Redirection to Untrusted Site ('Open Redirect') due to a misconfiguration flaw in the validation of redirect URIs. An attacker can redirect users to an arbitrary URL and potentially expose sensitive information such as authorization codes, leading to session hijacking.

    Note: This is only exploitable if a 'Valid Redirect URI' is set to http://localhost or http://127.0.0.1.
