Title
Keycloak-services: keycloak-services: client manager can substitute sessionless token principal via hardcoded-claim mappers to obtain realm administrator authority
Summary
A flaw was found in the protocol mapper and identity resolution components of Keycloak. The issue occurs when a client manager uses hardcoded-claim mappers to override identity claims in sessionless service-account tokens. Because these tokens lack a session ID, Keycloak may incorrectly resolve the token bearer as a different, highly privileged user based on the manipulated claims. This can allow an attacker with limited client management permissions to impersonate a realm administrator and gain full control over the realm.

Until patched, this is a concern on Keycloak deployments with OIDC clients configured for sessionless service-account tokens where delegated users hold manage-clients permissions, so Audit and restrict manage-clients permissions on OIDC clients, avoid using sessionless service-account tokens, and monitor client protocol mappers for unauthorized sub or preferred_username overrides. As a compensating measure, Detect unauthorized addition of hardcoded-claim protocol mappers to Keycloak OIDC client configurations by monitoring application configurations against a declared baseline via drift detection. These controls limit blast radius and contain exploitation, but they do not fix the underlying improper identity resolution defect \u2014 apply the upstream patch to fully remediate.\n\nHighest-impact CME: CME-1007 Application Configuration Drift Detection (IaC Enforcement) (medium)"

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
JSON API Auth <= 3.1.2 - Unauthenticated Authentication Bypass via Cached 'generate_auth_cookie' Response
Summary
The JSON API Auth plugin for WordPress is vulnerable to Authentication Bypass via Cached Session Cookie Disclosure in all versions up to, and including, 3.1.2. The vulnerability exists because the required PI-Media/json-api parent plugin caches controller dispatch results in transients keyed solely by URI and query string, ignoring HTTP method and POST body; this causes the `generate_auth_cookie()` endpoint — which embeds a live WordPress `logged_in` cookie produced by `wp_generate_auth_cookie()` directly in its JSON response body — to serve that cached authenticated response to any subsequent unauthenticated GET request to the same URI. This makes it possible for unauthenticated attackers to retrieve a valid Administrator `logged_in` session cookie from the cached response and use it to fully authenticate as the site Administrator, including via the same plugin's `get_currentuserinfo` endpoint and any cookie-authenticated controller action. Exploitation requires the PI-Media/json-api parent plugin to be installed and active with the Auth controller enabled, and a legitimate Administrator must have POSTed to `/api/auth/generate_auth_cookie/` within the preceding 24-hour cache TTL; the nominal HTTPS enforcement gate present in `Auth.php` is trivially bypassed by supplying `insecure=cool` as a request parameter.

Title
Keycloak-services: keycloak-services: dcr azp and sid claim substitution allows account rest session takeover
Summary
A flaw was found in the Keycloak Account REST API where it incorrectly handles session identification. A malicious client owner can manipulate their own security tokens to point to a different user's active session. This allows the attacker to access and modify the victim's account information, potentially leading to a full account takeover by changing the recovery email and resetting the password.

Title
Burst Statistics <= 3.7.1 - Improper Authentication to Account Persistence via Share-Link Authentication Bypass via 'burst_share_token'
Summary
The Burst Statistics – Simple WordPress Analytics (Google Analytics Alternative) plugin for WordPress is vulnerable to Improper Authentication leading to Account Persistence in all versions up to, and including, 3.7.1. This is due to the `maybe_load_shared_dashboard()` handler issuing a genuine WordPress session cookie for the `burst_statistics_viewer` account to any visitor presenting a valid share token via `wp_set_auth_cookie()`, while the plugin only blocks Application Passwords for the resulting `burst_viewer` role and does not restrict the core `/wp-json/wp/v2/users/me` password update endpoint or filter the `edit_user` capability for that account — leaving WordPress core's built-in rule that any authenticated user may update their own account fully in effect. This makes it possible for unauthenticated attackers to set an attacker-chosen password on the `burst_statistics_viewer` WordPress account, constituting a permanent takeover of that limited-privilege (`view_burst_statistics`) account that persists through share-token revocation, share-token expiration, and execution of the plugin's daily `cleanup_viewer_sessions()` routine. Exploitation requires that the attacker have obtained a valid `burst_share_token`, such as one that has been shared publicly or distributed to an untrusted party.

Title
Keycloak-services: keycloak-services: unverified idp email auto-linking enables account takeover
Summary
A flaw was found in the idp-auto-link authenticator of the keycloak-services component, which handles user identity federation. The issue occurs when Keycloak automatically links an incoming identity from an external provider to an existing local account based on an email address without verifying if the provider has validated that email. This can allow an attacker to take over a victim's account by using a matching unverified email address at a brokered provider.

This content was generated utilizing AI tools in conjunction with data from https://cmetaxonomy.org. Customers are advised to independently evaluate and test these temporary mitigations within their own infrastructure.\n\nThe highest-value action is to require verification of the email verified claim before linking brokered identities to local accounts in the idp-auto-link authenticator: upgrade to Red Hat build of Keycloak 26.4.17 (or the fixed Rhbk/Keycloak Rhel/Keycloak Services builds), which verify the email verified claim before automatically linking an incoming brokered identity to an existing local account, closing federated identity login using unverified matching email address. Until patched, this is a concern on Keycloak deployments configured with the idp-auto-link authenticator in the first-broker-login flow, so audit brokered external identity providers to ensure they enforce email verification, or avoid using external providers that permit arbitrary unverified email addresses matching existing local accounts. As a compensating measure, Enforce multi-factor authentication on target Keycloak accounts to prevent attackers from completing account takeovers even if the federated identity is automatically linked. These controls limit blast radius and contain exploitation, but they do not fix the underlying improper authentication defect \u2014 apply the upstream patch to fully remediate.\n\nHighest-impact CME: CME-801 Multi-Factor Authentication (MFA) (medium)"

Mitigation
Architecture and Design
Strategy: Libraries or Frameworks
Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
CAPEC-114: Authentication Abuse
An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker.
CAPEC-115: Authentication Bypass
An attacker gains access to application, service, or device with the privileges of an authorized or privileged user by evading or circumventing an authentication mechanism. The attacker is therefore able to access protected data without authentication ever having taken place.
CAPEC-151: Identity Spoofing
Identity Spoofing refers to the action of assuming (i.e., taking on) the identity of some other entity (human or non-human) and then using that identity to accomplish a goal. An adversary may craft messages that appear to come from a different principle or use stolen / spoofed authentication credentials.
CAPEC-194: Fake the Source of Data
An adversary takes advantage of improper authentication to provide data or services under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or to assume the rights granted to another individual. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. The root of the attack (in this case the email system) fails to properly authenticate the source and this results in the reader incorrectly performing the instructed action. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.
CAPEC-22: Exploiting Trust in Client
An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
CAPEC-57: Utilizing REST's Trust in the System Resource to Obtain Sensitive Data
This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to obtain sensitive data once SSL is terminated.
CAPEC-593: Session Hijacking
This type of attack involves an adversary that exploits weaknesses in an application's use of sessions in performing authentication. The adversary is able to steal or manipulate an active session and use it to gain unathorized access to the application.
CAPEC-633: Token Impersonation
An adversary exploits a weakness in authentication to create an access token (or equivalent) that impersonates a different entity, and then associates a process/thread to that that impersonated token. This action causes a downstream user to make a decision or take action that is based on the assumed identity, and not the response that blocks the adversary.
CAPEC-650: Upload a Web Shell to a Web Server
By exploiting insufficient permissions, it is possible to upload a web shell to a web server in such a way that it can be executed remotely. This shell can have various capabilities, thereby acting as a "gateway" to the underlying web server. The shell might execute at the higher permission level of the web server, providing the ability the execute malicious code at elevated levels.
CAPEC-94: Adversary in the Middle (AiTM)
An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components.
