CVE-2025-6024 is classified as a medium-severity vulnerability that impacts WSO2 products, specifically the API Manager and Identity Server. This vulnerability allows attackers to exploit an authentication endpoint that fails to properly encode user-supplied input before rendering it in web pages. As a result, attackers can inject malicious scripts into the application. The potential consequences include redirecting users' browsers to malicious websites, manipulating the web page's user interface, or retrieving sensitive information from users' browsers. However, due to the httpOnly flag protecting session-related cookies, session hijacking is not possible.
The vulnerability has a CVSS score of 6.1, which is classified as medium severity. This score indicates that while the vulnerability is not critical, it still poses a significant risk that organizations should take seriously. The attack vector is classified as 'network', which means that the vulnerability can be exploited remotely without requiring physical access to the affected systems.
Organizations using affected versions of WSO2 API Manager (3.1.0, 3.2.0, 3.2.1, 4.0.0, and 4.1.0) and WSO2 Identity Server (5.10.0 and 5.11.0) are at risk. The vulnerability was published on April 16, 2026, and organizations should prioritize patching to the latest versions to mitigate the risk.
Given the nature of this vulnerability, organizations should assess their exposure and take appropriate actions to secure their applications. Failing to address this vulnerability could lead to unauthorized access or manipulation of sensitive data.
Vulnerability Details
The authentication endpoint fails to encode user-supplied input before rendering it in the web page, allowing for script injection. This vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation. The official CVSS score of 6.1 reflects a medium severity level, implying that while the impacts are significant, they do not rise to critical levels. The details related to this vulnerability can be referenced from the WSO2 advisory.
Technical Analysis
The root cause of CVE-2025-6024 lies in the failure to properly sanitize user input in the authentication endpoint. This oversight allows attackers to exploit the web application by injecting scripts, which can execute in the context of a user's session. The attack vector is network-based, meaning that an attacker can initiate an attack remotely without needing direct access to the underlying systems.
The attack complexity is classified as low, indicating that it is relatively straightforward for an attacker to execute. No privileges are required for an attacker to exploit this vulnerability, making it particularly concerning for organizations. User interaction is required since the attacker must convince the user to interact with the malicious script, typically through social engineering tactics.
The impacts of this vulnerability include potential low confidentiality and integrity impacts, as attackers may gain access to sensitive information or manipulate the user interface. However, there is no impact on availability, making it a medium-risk concern for organizations.
Risk & Impact Analysis
Organizations utilizing WSO2 API Manager and Identity Server versions mentioned previously are at risk of exploitation of CVE-2025-6024. The vulnerability's impact is exacerbated by the low complexity required for exploitation and the lack of required privileges for attackers. Risk to organizations includes potential unauthorized access to sensitive user data, manipulation of web pages, and redirection to malicious sites. Given the CVSS score of 6.1, organizations should assess their defenses and prioritize remediation efforts.
The urgency for organizations to address this vulnerability is medium, as it does not currently appear in the KEV (Known Exploited Vulnerabilities) catalog. However, the risks posed by this vulnerability necessitate timely patching and remediation efforts.
