Title
Undertow: undertow: request smuggling via malformed http request headers
Summary
A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line starts with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This behavior, which violates HTTP standards, can be exploited by a remote attacker to perform request smuggling. Request smuggling allows an attacker to bypass security mechanisms, access restricted information, or manipulate web caches, potentially leading to unauthorized actions or data exposure.

Title
Keycloak: org.keycloak/keycloak-services: keycloak: privilege escalation via manage-clients permission
Summary
A flaw was found in Keycloak. An administrator with `manage-clients` permission can exploit a misconfiguration where this permission is equivalent to `manage-permissions`. This allows the administrator to escalate privileges and gain control over roles, users, or other administrative functions within the realm. This privilege escalation can occur when admin permissions are enabled at the realm level.
Severity ?
6.5 (Medium)

Title
Org.keycloak.protocol.oidc.grants: org.keycloak.services.managers: keycloak: server-side request forgery via oidc token endpoint manipulation
Summary
A flaw was found in Keycloak. An authenticated attacker can perform Server-Side Request Forgery (SSRF) by manipulating the `client_session_host` parameter during refresh token requests. This occurs when a Keycloak client is configured to use the `backchannel.logout.url` with the `application.session.host` placeholder. Successful exploitation allows the attacker to make HTTP requests from the Keycloak server’s network context, potentially probing internal networks or internal APIs, leading to information disclosure.

Title
Undertow: undertow: denial of service due to premature multipart/form-data parsing in get requests
Summary
A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending an HTTP GET request containing multipart/form-data content. If the underlying application processes parameters using methods like `getParameterMap()`, the server prematurely parses and stores this content to disk. This could lead to resource exhaustion, potentially resulting in a Denial of Service (DoS).
Severity ?
5.9 (Medium)

Title
Keycloak: org.keycloak.authorization: keycloak: unauthorized resource modification due to improper access control
Summary
A flaw was found in Keycloak. An improper Access Control vulnerability in Keycloak’s User-Managed Access (UMA) resource_set endpoint allows attackers with valid credentials to bypass the allowRemoteResourceManagement=false restriction. This occurs due to incomplete enforcement of access control checks on PUT operations to the resource_set endpoint. This issue enables unauthorized modification of protected resources, impacting data integrity.

Title
Keycloak-services: blind server-side request forgery (ssrf) via http redirect handling in keycloak
Summary
A flaw was identified in Keycloak, an identity and access management solution, where it improperly follows HTTP redirects when processing certain client configuration requests. This behavior allows an attacker to trick the server into making unintended requests to internal or restricted resources. As a result, sensitive internal services such as cloud metadata endpoints could be accessed. This issue may lead to information disclosure and enable attackers to map internal network infrastructure.

Configure firewall rules to prevent the Keycloak server from initiating connections to internal network segments, especially to well-known cloud metadata service IP addresses such as `169.254.169.254`. For example, on Red Hat Enterprise Linux, you can use `firewalld` to add a rich rule:\n`sudo firewall-cmd --permanent --zone=public --add-rich-rule=\u0027rule family=\"ipv4\" destination address=\"169.254.169.254\" reject\u0027`\n`sudo firewall-cmd --reload`\nThis may impact other services if they legitimately rely on accessing these internal IPs. Additionally, ensure that any configured `sector_identifier_uri` values are thoroughly validated to only point to trusted, external URLs that do not perform redirects to internal resources."

Title
Org.keycloak.services.resources.account: improper access control leading to mfa deletion and account takeover in keycloak account rest api
Summary
A flaw was identified in the Account REST API of Keycloak that allows a user authenticated at a lower security level to perform sensitive actions intended only for higher-assurance sessions. Specifically, an attacker who has already obtained a victim’s password can delete the victim’s registered MFA/OTP credential without first proving possession of that factor. The attacker can then register their own MFA device, effectively taking full control of the account. This weakness undermines the intended protection provided by multi-factor authentication.

Title
Org.keycloak/keycloak-services: improper enforcement of disabled identity provider in identitybrokerservice (authentication bypass)
Summary
A security flaw in the IdentityBrokerService.performLogin endpoint of Keycloak allows authentication to proceed using an Identity Provider (IdP) even after it has been disabled by an administrator. An attacker who knows the IdP alias can reuse a previously generated login request to bypass the administrative restriction. This undermines access control enforcement and may allow unauthorized authentication through a disabled external provider.

CVE-2026-2733 (GCVE-0-2026-2733)
Vulnerability from nvd – Published: 2026-02-19 07:48 – Updated: 2026-03-06 03:31

Title
Org.keycloak/keycloak-services: keycloak: missing check on disabled client for docker registry protocol
Summary
A flaw was identified in the Docker v2 authentication endpoint of Keycloak, where tokens continue to be issued even after a Docker registry client has been administratively disabled. This means that turning the client “Enabled” setting to OFF does not fully prevent access. As a result, previously valid credentials can still be used to obtain authentication tokens. This weakens administrative controls and could allow unintended access to container registry resources.

Title
Org.keycloak/keycloak-services: keycloak saml brokering: response delay due to unchecked notonorafter in subjectconfirmationdata
Summary
A flaw was found in Keycloak's SAML brokering functionality. When Keycloak is configured as a client in a Security Assertion Markup Language (SAML) setup, it fails to validate the `NotOnOrAfter` timestamp within the `SubjectConfirmationData`. This allows an attacker to delay the expiration of SAML responses, potentially extending the time a response is considered valid and leading to unexpected session durations or resource consumption.

Title
Undertow: undertow: request smuggling via malformed http request headers
Summary
A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line starts with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This behavior, which violates HTTP standards, can be exploited by a remote attacker to perform request smuggling. Request smuggling allows an attacker to bypass security mechanisms, access restricted information, or manipulate web caches, potentially leading to unauthorized actions or data exposure.
Severity ?
8.7 (High)

Title
Keycloak: org.keycloak/keycloak-services: keycloak: privilege escalation via manage-clients permission
Summary
A flaw was found in Keycloak. An administrator with `manage-clients` permission can exploit a misconfiguration where this permission is equivalent to `manage-permissions`. This allows the administrator to escalate privileges and gain control over roles, users, or other administrative functions within the realm. This privilege escalation can occur when admin permissions are enabled at the realm level.
Severity ?
6.5 (Medium)

Org.keycloak.protocol.oidc.grants: org.keycloak.services.managers: keycloak: server-side request forgery via oidc token endpoint manipulation
Summary
A flaw was found in Keycloak. An authenticated attacker can perform Server-Side Request Forgery (SSRF) by manipulating the `client_session_host` parameter during refresh token requests. This occurs when a Keycloak client is configured to use the `backchannel.logout.url` with the `application.session.host` placeholder. Successful exploitation allows the attacker to make HTTP requests from the Keycloak server’s network context, potentially probing internal networks or internal APIs, leading to information disclosure.

Title
Undertow: undertow: denial of service due to premature multipart/form-data parsing in get requests
Summary
A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending an HTTP GET request containing multipart/form-data content. If the underlying application processes parameters using methods like `getParameterMap()`, the server prematurely parses and stores this content to disk.

Title
Keycloak: org.keycloak.authorization: keycloak: unauthorized resource modification due to improper access control
Summary
A flaw was found in Keycloak. An improper Access Control vulnerability in Keycloak’s User-Managed Access (UMA) resource_set endpoint allows attackers with valid credentials to bypass the allowRemoteResourceManagement=false restriction. This occurs due to incomplete enforcement of access control checks on PUT operations to the resource_set endpoint. This issue enables unauthorized modification of protected resources, impacting data integrity.

Title
Keycloak-services: blind server-side request forgery (ssrf) via http redirect handling in keycloak
Summary
A flaw was identified in Keycloak, an identity and access management solution, where it improperly follows HTTP redirects when processing certain client configuration requests. This behavior allows an attacker to trick the server into making unintended requests to internal or restricted resources. As a result, sensitive internal services such as cloud metadata endpoints could be accessed. This issue may lead to information disclosure and enable attackers to map internal network infrastructure.

"value": "To mitigate this vulnerability, restrict the outbound network access of the Keycloak instance. Configure firewall rules to prevent the Keycloak server from initiating connections to internal network segments, especially to well-known cloud metadata service IP addresses such as `169.254.169.254`. For example, on Red Hat Enterprise Linux, you can use `firewalld` to add a rich rule:\n`sudo firewall-cmd --permanent --zone=public --add-rich-rule=\u0027rule family=\"ipv4\" destination address=\"169.254.169.254\" reject\u0027`\n`sudo firewall-cmd --reload`\nThis may impact other services if they legitimately rely on accessing these internal IPs. Additionally, ensure that any configured `sector_identifier_uri` values are thoroughly validated to only point to trusted, external URLs that do not perform redirects to internal resources."

Title
Org.keycloak.services.resources.account: improper access control leading to mfa deletion and account takeover in keycloak account rest api
Summary
A flaw was identified in the Account REST API of Keycloak that allows a user authenticated at a lower security level to perform sensitive actions intended only for higher-assurance sessions. Specifically, an attacker who has already obtained a victim’s password can delete the victim’s registered MFA/OTP credential without first proving possession of that factor. The attacker can then register their own MFA device, effectively taking full control of the account. This weakness undermines the intended protection provided by multi-factor authentication.

Title
Org.keycloak/keycloak-services: improper enforcement of disabled identity provider in identitybrokerservice (authentication bypass)
Summary
A security flaw in the IdentityBrokerService.performLogin endpoint of Keycloak allows authentication to proceed using an Identity Provider (IdP) even after it has been disabled by an administrator. An attacker who knows the IdP alias can reuse a previously generated login request to bypass the administrative restriction. This undermines access control enforcement and may allow unauthorized authentication through a disabled external provider.

Summary
A flaw was found in Keycloak. An administrator with `manage-users` permission can bypass the "Only administrators can view" setting for unmanaged attributes, allowing them to modify these attributes. This improper access control can lead to unauthorized changes to user profiles, even when the system is configured to restrict such modifications.

CVE-2026-2733 (GCVE-0-2026-2733)
Vulnerability from cvelistv5 – Published: 2026-02-19 07:48 – Updated: 2026-03-06 03:31

Title
Org.keycloak/keycloak-services: keycloak: missing check on disabled client for docker registry protocol
Summary
A flaw was identified in the Docker v2 authentication endpoint of Keycloak, where tokens continue to be issued even after a Docker registry client has been administratively disabled. This means that turning the client “Enabled” setting to OFF does not fully prevent access. As a result, previously valid credentials can still be used to obtain authentication tokens. This weakens administrative controls and could allow unintended access to container registry resources.

Title
Org.keycloak/keycloak-services: keycloak saml brokering: response delay due to unchecked notonorafter in subjectconfirmationdata
Summary
A flaw was found in Keycloak's SAML brokering functionality. When Keycloak is configured as a client in a Security Assertion Markup Language (SAML) setup, it fails to validate the `NotOnOrAfter` timestamp within the `SubjectConfirmationData`. This allows an attacker to delay the expiration of SAML responses, potentially extending the time a response is considered valid and leading to unexpected session durations or resource consumption.
Severity ?
