Recent Wso2 Open Banking Iam Security Vulnerabilities
WSO2 IDS Auth Flow Bypass via Conditional Auth Script
CVE-2025-15039
9.4 - Critical
- August 06, 2026
The Conditional Authentication (Adaptive Authentication) script does not correctly enforce the completion of all required authentication steps when a specific multi-step pattern involving certain authenticators is configured. This allows an attacker to bypass intermediate authentication challenges by exploiting how the script handles callbacks and re-execution of authentication steps. Successful exploitation allows a malicious actor to gain unauthorized access to a targeted user account. This vulnerability can only be exploited when all of the following conditions are met: the application login flow contains a specific secondary authenticator, the Conditional Authentication script is configured with particular event callbacks and re-executes an authentication step, the targeted user has one of the impacted authenticators enrolled, and the attacker successfully completes any preceding authentication steps.
Protection Mechanism Failure
WSO2 Carbon Event Publisher Log Bypass via Misconfigured Adapter
CVE-2026-0637
4.4 - Medium
- August 06, 2026
When an Event Publisher output adapter is configured with irrelevant properties, the affected products log these properties. This logging occurs without sufficient validation or sanitization of the property values. A malicious actor with access to the 'wso2carbon' log files could retrieve sensitive information, such as user credentials or other confidential data, that was inadvertently logged due to misconfiguration, potentially leading to unauthorized access.
Insertion of Sensitive Information into Log File
CSRF via GET in WSO2 Carbon Console Ajax Processor
CVE-2025-13394
5.4 - Medium
- August 06, 2026
The Ajax processor within the Carbon console fails to adequately protect state-changing operations from Cross-Site Request Forgery (CSRF) attacks. Specifically, it utilizes the HTTP GET method for these operations, and while the SameSite=Lax cookie attribute is employed for mitigation, this mechanism is bypassed as it permits cookies to be sent with cross-origin top-level navigation requests, including GET requests. This allows an attacker to trick an authenticated user's browser into unknowingly executing unintended actions. An attacker can exploit this vulnerability to perform unauthorized state-altering requests on behalf of authenticated users. This could lead to consequences such as data modification, account changes, or other actions that could result in data compromise or loss of user control over their account. However, this attack is only feasible if the Carbon console and related services are exposed to the public internet, which is not recommended according to WSO2's security guidelines.
Session Riding
WSO2 Identity Server: Username Enumeration via Multi-Attribute Login
CVE-2025-13736
3.7 - Low
- August 06, 2026
When Multi-Attribute Login is enabled, the login interface fails to consistently mask the existence of user accounts. For valid users, the server resolves and displays their canonical username, while for non-existent users, it echoes the original input. This occurs regardless of the validate_username configuration. The discovery of valid usernames can increase the risk of brute force attacks, social engineering attacks, and targeted information leakage. Attackers can leverage this information to craft more effective phishing campaigns or social engineering tactics to compromise user accounts or extract sensitive data.
Side Channel Attack
WSO2 Unvalidated Claims Injection in User SelfSignup
CVE-2024-10302
4 - Medium
- August 06, 2026
The user self-signup flow in multiple WSO2 products fails to adequately validate user-supplied input. This weakness allows arbitrary unvalidated data to be included within user claims, which are then used by downstream processes. Allowing unvalidated input into user claims can lead to various security risks. Malicious or malformed data injected during signup could be processed by other parts of the application, potentially enabling attacks such as content manipulation, redirection, user interface inconsistencies, unauthorized actions, and data exposure. The actual impact depends on how the compromised data is consumed and the privileges associated with the affected users.
Improper Input Validation
WSO2 Identity Server Account Lockout Bypass via Unreachable User Store
CVE-2024-6832
5.9 - Medium
- August 06, 2026
The account locking mechanism fails to trigger when secondary user stores are inaccessible. The software does not maintain a consistent state for account locking if it cannot reach all configured user stores, allowing an attacker to repeatedly attempt authentication with invalid credentials without triggering the lockout mechanism for users within active stores. When the account locking mechanism is bypassed due to the inaccessibility of secondary user stores, users in accessible user stores are left vulnerable to brute force attacks. A malicious actor can exploit this by attempting numerous invalid password combinations against a user account without the expected account lockout consequence.
Protection Mechanism Failure
Auth Code Leakage in WSO2 Identity Server Allows Token Abuse
CVE-2024-8995
4.9 - Medium
- August 06, 2026
Unused authorization codes issued to deleted users are not being properly invalidated or removed from the system. This allows for the persistence of these codes, enabling them to be potentially reused. If an attacker possesses both the authorization code and the associated client credentials (client ID and client secret), they can leverage these unused codes to obtain access tokens on behalf of users who have already been deleted. This may lead to unauthorized access to sensitive resources and services, contingent on the scopes originally authorized for the compromised authorization code.
Insufficient Session Expiration
Reflected XSS via URL Param in WSO2 API Manager
CVE-2025-8591
6.1 - Medium
- July 06, 2026
The software accepts user-supplied input via a URL parameter without adequate output encoding before reflecting it back to the user's browser. This condition allows an attacker to inject malicious script content into pages served by the application. By leveraging this weakness, an attacker can cause the user's browser to redirect to a malicious website, modify the UI of the webpage, or retrieve information from the browser. However, the impact is mitigated by the use of httpOnly flags on session-related cookies, preventing session hijacking.
XSS
WSO2 ID Server JIT Provisioning Role Overwrite via Username Collision
CVE-2024-1248
4.8 - Medium
- July 04, 2026
The silent Just-In-Time (JIT) provisioning feature in federated authentication implementations fails to properly segregate user roles during account creation when a federated user shares a username with a local user. This allows the provisioning process to overwrite existing roles of local users with roles assigned to the federated user. Exploitation requires a federated identity provider (IDP) with silent JIT provisioning enabled and an attacker's knowledge of a local user's username. When these conditions are met, a malicious individual can leverage the JIT provisioning process to modify the roles of local users. The overwritten roles are limited to those defined within the federated IDP, typically granting minimal access rights unless explicitly configured otherwise by the federated IDP administrator.
Improper Validation of Certificate Expiration
WSO2 Identity Server: OTP Account Lock State Bypass Allows Username Enumeration
CVE-2024-0391
5.3 - Medium
- May 11, 2026
The check user account lock states feature within the email OTP flow fails to validate user input, allowing an attacker to infer the existence of registered user accounts. The discovery of valid usernames can increase the risk of brute-force and social engineering attacks. Attackers can leverage this information to craft targeted phishing campaigns or other malicious activities aimed at tricking users into divulging sensitive data, potentially damaging the organization's reputation and leading to regulatory non-compliance and financial consequences.
Observable Response Discrepancy
WSO2 XML External Entity (XXE) In Parser Vulnerability
CVE-2024-2374
7.5 - High
- April 16, 2026
The XML parsers within multiple WSO2 products accept user-supplied XML data without properly configuring to prevent the resolution of external entities. This omission allows malicious actors to craft XML payloads that exploit the parser's behavior, leading to the inclusion of external resources. By leveraging this vulnerability, an attacker can read confidential files from the file system and access limited HTTP resources reachable by the product. Additionally, the vulnerability can be exploited to perform denial of service attacks by exhausting server resources through recursive entity expansion or fetching large external resources.
XXE
Authx Bypass in WSO2 Identity Server mTLS Auth Flow
CVE-2025-9312
9.8 - Critical
- November 18, 2025
A missing authentication enforcement vulnerability exists in the mutual TLS (mTLS) implementation used by System REST APIs and SOAP services in multiple WSO2 products. Due to improper validation of client certificatebased authentication in certain default configurations, the affected components may permit unauthenticated requests even when mTLS is enabled. This condition occurs when relying on the default mTLS settings for System REST APIs or when the mTLS authenticator is enabled for SOAP services, causing these interfaces to accept requests without enforcing additional authentication. Successful exploitation allows a malicious actor with network access to the affected endpoints to gain administrative privileges and perform unauthorized operations. The vulnerability is exploitable only when the impacted mTLS flows are enabled and accessible in a given deployment. Other certificate-based authentication mechanisms such as Mutual TLS OAuth client authentication and X.509 login flows are not affected, and APIs served through the API Gateway of WSO2 API Manager remain unaffected.
Missing Authentication for Critical Function
WSO2 Mgt Console Reflected XSS via Improper Output Encoding
CVE-2025-10853
5.2 - Medium
- November 05, 2025
A reflected cross-site scripting (XSS) vulnerability exists in the management console of multiple WSO2 products due to improper output encoding. By tampering with specific parameters, a malicious actor can inject arbitrary JavaScript into the response, leading to reflected XSS. Successful exploitation could result in UI manipulation, redirection to malicious websites, or data theft from the browser. However, session-related sensitive cookies are protected with the httpOnly flag, which mitigates the risk of session hijacking.
XSS
Arbitrary Code Exec via Unrestricted GraalJS/NashornJS in WSO2 Integrators
CVE-2025-11093
8.4 - High
- November 05, 2025
An arbitrary code execution vulnerability exists in multiple WSO2 products due to insufficient restrictions in the GraalJS and NashornJS Script Mediator engines. Authenticated users with elevated privileges can execute arbitrary code within the integration runtime environment. By default, access to these scripting engines is limited to administrators in WSO2 Micro Integrator and WSO2 Enterprise Integrator, while in WSO2 API Manager, access extends to both administrators and API creators. This may allow trusted-but-privileged users to perform unauthorized actions or compromise the execution environment.
Code Injection
WSO2 Admin SOAP Services Arbitrary File Upload (RCE)
CVE-2025-10907
8.4 - High
- November 05, 2025
An arbitrary file upload vulnerability exists in multiple WSO2 products due to insufficient validation of uploaded content and destination in SOAP admin services. A malicious actor with administrative privileges can upload a specially crafted file to a user-controlled location within the deployment. Successful exploitation may lead to remote code execution (RCE) on the server, depending on how the uploaded file is processed. By default, this vulnerability is only exploitable by users with administrative access to the affected SOAP services.
Unrestricted File Upload
XXE Vulnerability in WSO2 XML Parser
CVE-2025-10713
6.5 - Medium
- November 05, 2025
An XML External Entity (XXE) vulnerability exists in multiple WSO2 products due to improper configuration of the XML parser. The application parses user-supplied XML without applying sufficient restrictions, allowing resolution of external entities. A successful attack could enable a remote, unauthenticated attacker to read sensitive files from the server's filesystem or perform denial-of-service (DoS) attacks that render affected services unavailable.
XXE
WSO2 Carbon AppUploader Authenticated File Upload Vulnerability (RCE)
CVE-2025-3125
6.7 - Medium
- November 05, 2025
An arbitrary file upload vulnerability exists in multiple WSO2 products due to improper input validation in the CarbonAppUploader admin service endpoint. An authenticated attacker with appropriate privileges can upload a malicious file to a user-controlled location on the server, potentially leading to remote code execution (RCE). This functionality is restricted by default to admin users; therefore, successful exploitation requires valid credentials with administrative permissions.
Unrestricted File Upload
WSO2 Management Console Auth Bypass via URI Manipulation
CVE-2025-5605
4.3 - Medium
- October 24, 2025
An authentication bypass vulnerability exists in the Management Console of multiple WSO2 products. A malicious actor with access to the console can manipulate the request URI to bypass authentication and access certain restricted resources, resulting in partial information disclosure. The known exposure from this issue is limited to memory statistics. While the vulnerability does not allow full account compromise, it still enables unauthorized access to internal system details.
Authentication Bypass by Spoofing
WSO2 IS Privilege Escalation via SOAP Admin Role Injection
CVE-2024-7096
4.2 - Medium
- May 30, 2025
A privilege escalation vulnerability exists in multiple WSO2 products due to a business logic flaw in SOAP admin services. A malicious actor can create a new user with elevated permissions only when all of the following conditions are met: * SOAP admin services are accessible to the attacker. * The deployment includes an internally used attribute that is not part of the default WSO2 product configuration. * At least one custom role exists with non-default permissions. * The attacker has knowledge of the custom role and the internal attribute used in the deployment. Exploiting this vulnerability allows malicious actors to assign higher privileges to self-registered users, bypassing intended access control mechanisms.
