Recent Red Hat Build Of Keycloak Security Vulnerabilities
Keycloak FGAPv2 Priv Escalation via Manage-Users Role
CVE-2025-7784
6.5 - Medium
- July 18, 2025
A flaw was found in the Keycloak identity and access management system when Fine-Grained Admin Permissions(FGAPv2) are enabled. An administrative user with the manage-users role can escalate their privileges to realm-admin due to improper privilege enforcement. This vulnerability allows unauthorized elevation of access rights, compromising the intended separation of administrative duties and posing a security risk to the realm.
Improper Privilege Management
Keycloak org.keycloak.auth bypass of required actions (2FA)
CVE-2025-3910
5.4 - Medium
- April 29, 2025
A flaw was found in Keycloak. The org.keycloak.authorization package may be vulnerable to circumventing required actions, allowing users to circumvent requirements such as setting up two-factor authentication.
authentification
XSS in WildFly Deployment System Enables RCE
CVE-2024-10234
6.1 - Medium
- October 22, 2024
A vulnerability was found in Wildfly, where a user may perform Cross-site scripting in the Wildfly deployment system. This flaw allows an attacker or insider to execute a deployment with a malicious payload, which could trigger undesired behavior against the server.
XSS
Keycloak Redirect URI: http://localhost Misconfig allows session hijack
CVE-2024-8883
6.1 - Medium
- September 19, 2024
A misconfiguration flaw was found in Keycloak. This issue can allow an attacker to redirect users to an arbitrary URL if a 'Valid Redirect URI' is set to http://localhost or http://127.0.0.1, enabling sensitive information such as authorization codes to be exposed to the attacker, potentially leading to session hijacking.
Open Redirect
Keycloak SAML adapters: session fixation via stale JSESSIONID cookie
CVE-2024-7341
7.1 - High
- September 09, 2024
A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the current session before authentication to trigger session fixation.
Session Fixation
Keycloak expired OTP tokens still valid 30s after expiry (FreeOTP)
CVE-2024-7318
4.8 - Medium
- September 09, 2024
A vulnerability was found in Keycloak. Expired OTP codes are still usable when using FreeOTP when the OTP token period is set to 30 seconds (default). Instead of expiring and deemed unusable around 30 seconds in, the tokens are valid for an additional 30 seconds totaling 1 minute. A one time passcode that is valid longer than its expiration time increases the attack window for malicious actors to abuse the system and compromise accounts. Additionally, it increases the attack surface because at any given time, two OTPs are valid.
Use of a Key Past its Expiration Date
Keycloak Open Redirect via referrer_uri Phishing Risk
CVE-2024-7260
6.1 - Medium
- September 09, 2024
An open redirect vulnerability was found in Keycloak. A specially crafted URL can be constructed where the referrer and referrer_uri parameters are made to trick a user to visit a malicious webpage. A trusted URL can trick users and automation into believing that the URL is safe, when, in fact, it redirects to a malicious server. This issue can result in a victim inadvertently trusting the destination of the redirect, potentially leading to a successful phishing attack or other types of attacks. Once a crafted URL is made, it can be sent to a Keycloak admin via email for example. This will trigger this vulnerability when the user visits the page and clicks the link. A malicious actor can use this to target users they know are Keycloak admins for further attacks. It may also be possible to bypass other domain-related security checks, such as supplying this as a OAuth redirect uri. The malicious actor can further obfuscate the redirect_uri using URL encoding, to hide the text of the actual malicious website domain.
Open Redirect
Keycloak Login Timing Bypass Allows Exceeding Brute Force Limits
CVE-2024-4629
6.5 - Medium
- September 03, 2024
A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems.
Improper Enforcement of a Single, Unique Action
Undertow ProxyProtocolReadListener StringBuilder reuse info-leak
CVE-2024-7885
7.5 - High
- August 21, 2024
A vulnerability was found in Undertow where the ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes multiple requests on the same HTTP connection. As a result, different requests may share the same StringBuilder instance, potentially leading to information leakage between requests or responses. In some cases, a value from a previous request or response may be erroneously reused, which could lead to unintended data exposure. This issue primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments.
Race Condition
Keycloak Re-authentication Session Hijacking (prompt=login)
CVE-2023-6787
6.5 - Medium
- April 25, 2024
A flaw was found in Keycloak that occurs from an error in the re-authentication mechanism within org.keycloak.authentication. This flaw allows hijacking an active Keycloak session by triggering a new authentication process with the query parameter "prompt=login," prompting the user to re-enter their credentials. If the user cancels this re-authentication by selecting "Restart login," an account takeover may occur, as the new session, with a different SUB, will possess the same SID as the previous session.
authentification
Keycloak Redirect URI Validation Bypass via Wildcard URIs
CVE-2024-1132
8.1 - High
- April 17, 2024
A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. This issue could allow an attacker to construct a malicious request to bypass validation and access other URLs and sensitive information within the domain or conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field, and requires user interaction within the malicious URL.
