Title
Keycloak-services: keycloak-services: smtp starttls plaintext credential and message downgrade
Summary
A flaw was found in the SMTP email configuration handling of the keycloak-services component. When the STARTTLS option is enabled, Keycloak fails to strictly enforce an encrypted connection, allowing it to fall back to unencrypted communication if the encryption request is tampered with. An attacker who can intercept network traffic can exploit this to capture sensitive email credentials and message content in plain text.

Title
Keycloak-services: keycloak-services: device authorization grant bypasses per-client minimum.acr.value enforcement
Summary
A flaw was found in the OIDC implementation of Keycloak, specifically within the Device Authorization Grant flow. This component allows devices with limited input capabilities to obtain security tokens. The issue occurs because the flow fails to check the minimum authentication level required by a client configuration. This allows an attacker who has stolen a user's password to bypass mandatory multi-factor authentication and gain unauthorized access to the Keycloak Admin REST API.

Title
Keycloak-services: keycloak-services: token introspection audience bypass via dynamic client registration
Summary
A flaw was found in the Dynamic Client Registration flow of the Keycloak identity and access management server. The issue occurs because the registration process fails to filter security-sensitive client attributes when a new client is created. An attacker with a valid Initial Access Token can register a client that bypasses audience checks during token introspection. This allows the attacker to view sensitive identity information, roles, and session details from access tokens belonging to other applications in the same realm.

Title
Keycloak-services: keycloak-services: user session note mapper exposes upstream idp access tokens
Summary
A flaw was found in the User Session Note mapper of the Keycloak identity and access management solution. The issue occurs because the mapper does not validate whether a requested session note contains sensitive internal credentials, such as federated access tokens from external identity providers. This allows a delegated client administrator to leak a user's upstream bearer tokens into the tokens issued to their managed application, potentially leading to unauthorized access to the user's data on external platforms.

Title
Keycloak-services: keycloak-services: blind ssrf via x.509 authenticator fetching attacker-controlled crl-dp/ocsp urls
Summary
A flaw was found in the X.509 client-certificate authenticator of Keycloak, a solution for identity and access management. The issue occurs when the server is configured to check certificate revocation using CRL Distribution Points or OCSP. An attacker can provide a specially crafted certificate that points to a malicious server, causing Keycloak to make unauthorized outbound requests to internal or external endpoints before the certificate is fully validated. This can lead to a blind server-side request forgery (SSRF) attack.

Title
Keycloak-services: keycloak-services: path traversal in x.509 crl distribution point allows arbitrary local file read
Summary
A flaw was found in the X.509 client certificate authenticator of Keycloak. When CRL Distribution Point checking is enabled, the server fails to properly validate the file paths provided in a client certificate. An attacker can provide a specially crafted certificate that causes the server to attempt to read sensitive files from the local system or exhaust memory by loading extremely large files, potentially leading to information disclosure or a system crash.

Title
Keycloak-services: keycloak-services: unbounded metric series creation via idp tag on broker login endpoint
Summary
A flaw was found in the Micrometer user-event metrics listener of Keycloak, a solution for integrated identity and access management. The issue occurs when the listener is configured to include the idp tag. An unauthenticated attacker can send requests to the identity broker login endpoint using arbitrary provider aliases, causing the system to create an unlimited number of metric time series. This can lead to excessive memory consumption and degrade the performance of both the server and its monitoring tools.

Title
Keycloak-services: keycloak-services: fgap v2 composite-blind role mapping allows privilege escalation
Summary
A flaw was found in the Fine-Grained Admin Permissions (FGAP v2) feature of Keycloak, an identity and access management solution. The issue occurs when the system checks if a delegated administrator has permission to assign a specific role to a user. Because the check does not look inside composite roles to see what other permissions they contain, an administrator with limited rights can assign a role that secretly includes full administrative control. This allows the attacker to gain complete management access over the entire realm.

Title
Keycloak-services: keycloak-services: standard token exchange v2 bypasses mtls holder-of-key binding
Summary
Keycloak provides a feature called mTLS holder-of-key binding which ensures that a token can only be used by the client that originally requested it by binding it to their digital certificate. A flaw was discovered where the new Standard Token Exchange V2 feature does not check for this certificate. This allows an attacker with stolen client credentials to obtain a standard, unrestricted token that bypasses these security protections.

Title
Keycloak-services: keycloak-services: admin rest api role-groups endpoint discloses groups without authorization
Summary
A flaw was found in the Admin REST API of Keycloak, an identity and access management solution. The endpoints used to retrieve groups associated with a specific role do not properly check for individual group visibility permissions. This allows a delegated administrator with basic search privileges to view detailed information about all groups assigned to a role, bypassing intended security restrictions that should limit their view to specific groups.

Title
Keycloak-services: keycloak-services: generic user update bypasses denied reset-password permission
Summary
A flaw was found in the user update mechanism of the Keycloak Admin REST API. When Fine-Grained Admin Permissions are enabled, the system fails to check for specific password reset authorizations during a general user profile update. This allows a delegated administrator, who should be restricted from resetting passwords, to change a user's credentials and take over their account.

Title
Keycloak-services: keycloak-services: essential acr requirement silently bypassed via cookie authenticator
Summary
A flaw was found in the Level of Authentication enforcement mechanism of Keycloak, an identity and access management solution. The issue occurs when a client specifically requires a higher security level for a user who already has an active session at a lower level. Due to a logic error in how session re-evaluations are handled, Keycloak may incorrectly issue a token at the lower security level instead of enforcing the required higher level, potentially allowing unauthorized access to sensitive resources that rely on these security claims.

Title
Keycloak-services: keycloak-services: par single-use bypass via prompt=none silent authentication path
Summary
A flaw was found in the Pushed Authorization Request PAR implementation of Keycloak. The issue occurs when the silent authentication path prompt=none is used, which allows the authorization process to skip certain steps if a user is already logged in. Due to this bypass, the security rule that ensures a pushed request URI is used only once is not enforced. An attacker could potentially reuse a request URI to obtain multiple authorization codes for a user who is already signed in, violating security standards like FAPI-2.

Title
Keycloak-services: keycloak-services: conditional otp skip-header policy evaluated against untrusted proxy headers
Summary
A flaw was found in the Conditional OTP authenticator of Keycloak, an identity and access management solution. The issue occurs when the system evaluates specific HTTP headers to determine if a one-time password (OTP) should be skipped, but fails to verify if those headers came from a trusted source. This could allow an attacker who already has a user's password to bypass the second-factor authentication by providing a specially crafted header in their request.

Title
Keycloak-services: keycloak-services: potential kdc spoofing bypass when kerberos password authentication is enabled
Summary
A flaw was found in the Kerberos federation provider of Keycloak, an open-source identity and access management solution. When Kerberos password authentication is used without SPNEGO, the system fails to verify the identity of the Key Distribution Center (KDC) by requesting a server ticket. This allows an attacker on the same network to spoof the KDC and bypass the authentication process, potentially gaining unauthorized access to user accounts.

Title
Keycloak-services: keycloak-services: smtp starttls plaintext credential and message downgrade
Summary
A flaw was found in the SMTP email configuration handling of the keycloak-services component. When the STARTTLS option is enabled, Keycloak fails to strictly enforce an encrypted connection, allowing it to fall back to unencrypted communication if the encryption request is tampered with. An attacker who can intercept network traffic can exploit this to capture sensitive email credentials and message content in plain text.

Keycloak-services: keycloak-services: device authorization grant bypasses per-client minimum.acr.value enforcement
Summary
A flaw was found in the OIDC implementation of Keycloak, specifically within the Device Authorization Grant flow. This component allows devices with limited input capabilities to obtain security tokens. The issue occurs because the flow fails to check the minimum authentication level required by a client configuration. This allows an attacker who has stolen a user's password to bypass mandatory multi-factor authentication and gain unauthorized access to the Keycloak Admin REST API.

Title
Keycloak-services: keycloak-services: token introspection audience bypass via dynamic client registration
Summary
A flaw was found in the Dynamic Client Registration flow of the Keycloak identity and access management server. The issue occurs because the registration process fails to filter security-sensitive client attributes when a new client is created. An attacker with a valid Initial Access Token can register a client that bypasses audience checks during token introspection. This allows the attacker to view sensitive identity information, roles, and session details from access tokens belonging to other applications in the same realm.

Title
Keycloak-services: keycloak-services: user session note mapper exposes upstream idp access tokens
Summary
A flaw was found in the User Session Note mapper of the Keycloak identity and access management solution. The issue occurs because the mapper does not validate whether a requested session note contains sensitive internal credentials, such as federated access tokens from external identity providers. This allows a delegated client administrator to leak a user's upstream bearer tokens into the tokens issued to their managed application, potentially leading to unauthorized access to the user's data on external platforms.

Title
Keycloak-services: keycloak-services: blind ssrf via x.509 authenticator fetching attacker-controlled crl-dp/ocsp urls
Summary
A flaw was found in the X.509 client-certificate authenticator of Keycloak, a solution for identity and access management. The issue occurs when the server is configured to check certificate revocation using CRL Distribution Points or OCSP. An attacker can provide a specially crafted certificate that points to a malicious server, causing Keycloak to make unauthorized outbound requests to internal or external endpoints before the certificate is fully validated. This can lead to a blind server-side request forgery (SSRF) attack.

Keycloak-services: keycloak-services: path traversal in x.509 crl distribution point allows arbitrary local file read
Summary
A flaw was found in the X.509 client certificate authenticator of Keycloak. When CRL Distribution Point checking is enabled, the server fails to properly validate the file paths provided in a client certificate. An attacker can provide a specially crafted certificate that causes the server to attempt to read sensitive files from the local system or exhaust memory by loading extremely large files, potentially leading to information disclosure or a system crash.

Title
Keycloak-services: keycloak-services: unbounded metric series creation via idp tag on broker login endpoint
Summary
A flaw was found in the Micrometer user-event metrics listener of Keycloak, a solution for integrated identity and access management. The issue occurs when the listener is configured to include the idp tag. An unauthenticated attacker can send requests to the identity broker login endpoint using arbitrary provider aliases, causing the system to create an unlimited number of metric time series. This can lead to excessive memory consumption and degrade the performance of both the server and its monitoring tools.

Title
Keycloak-services: keycloak-services: fgap v2 composite-blind role mapping allows privilege escalation
Summary
A flaw was found in the Fine-Grained Admin Permissions (FGAP v2) feature of Keycloak, an identity and access management solution. The issue occurs when the system checks if a delegated administrator has permission to assign a specific role to a user. Because the check does not look inside composite roles to see what other permissions they contain, an administrator with limited rights can assign a role that secretly includes full administrative control. This allows the attacker to gain complete management access over the entire realm.

Title
Keycloak-services: keycloak-services: standard token exchange v2 bypasses mtls holder-of-key binding
Summary
Keycloak provides a feature called mTLS holder-of-key binding which ensures that a token can only be used by the client that originally requested it by binding it to their digital certificate. A flaw was discovered where the new Standard Token Exchange V2 feature does not check for this certificate. This allows an attacker with stolen client credentials to obtain a standard, unrestricted token that bypasses these security protections.

Title
Keycloak-services: keycloak-services: admin rest api role-groups endpoint discloses groups without authorization
Summary
A flaw was found in the Admin REST API of Keycloak, an identity and access management solution. The endpoints used to retrieve groups associated with a specific role do not properly check for individual group visibility permissions. This allows a delegated administrator with basic search privileges to view detailed information about all groups assigned to a role, bypassing intended security restrictions that should limit their view to specific groups.

Title
Keycloak-services: keycloak-services: generic user update bypasses denied reset-password permission
Summary
A flaw was found in the user update mechanism of the Keycloak Admin REST API. When Fine-Grained Admin Permissions are enabled, the system fails to check for specific password reset authorizations during a general user profile update. This allows a delegated administrator, who should be restricted from resetting passwords, to change a user's credentials and take over their account.

Title
Keycloak-services: keycloak-services: essential acr requirement silently bypassed via cookie authenticator
Summary
A flaw was found in the Level of Authentication enforcement mechanism of Keycloak, an identity and access management solution. The issue occurs when a client specifically requires a higher security level for a user who already has an active session at a lower level. Due to a logic error in how session re-evaluations are handled, Keycloak may incorrectly issue a token at the lower security level instead of enforcing the required higher level, potentially allowing unauthorized access to sensitive resources that rely on these security claims.

Title
Keycloak-services: keycloak-services: conditional otp skip-header policy evaluated against untrusted proxy headers
Summary
A flaw was found in the Conditional OTP authenticator of Keycloak, an identity and access management solution. The issue occurs when the system evaluates specific HTTP headers to determine if a one-time password (OTP) should be skipped, but fails to verify if those headers came from a trusted source. This could allow an attacker who already has a user's password to bypass the second-factor authentication by providing a specially crafted header in their request.

Title
Keycloak-services: keycloak-services: par single-use bypass via prompt=none silent authentication path
Summary
A flaw was found in the Pushed Authorization Request PAR implementation of Keycloak. The issue occurs when the silent authentication path prompt=none is used, which allows the authorization process to skip certain steps if a user is already logged in. Due to this bypass, the security rule that ensures a pushed request URI is used only once is not enforced. An attacker could potentially reuse a request URI to obtain multiple authorization codes for a user who is already signed in, violating security standards like FAPI-2.

Title
Keycloak-services: keycloak-services: potential kdc spoofing bypass when kerberos password authentication is enabled
Summary
A flaw was found in the Kerberos federation provider of Keycloak, an open-source identity and access management solution. When Kerberos password authentication is used without SPNEGO, the system fails to verify the identity of the Key Distribution Center (KDC) by requesting a server ticket. This allows an attacker on the same network to spoof the KDC and bypass the authentication process, potentially gaining unauthorized access to user accounts.
