Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The authentication endpoint fails to encode user-supplied input before rendering it in the web page, allowing for script injection. An attacker can leverage this by injecting malicious scripts into the authentication endpoint. This can result in the user's browser being redirected to a malicious website, manipulation of the web page's user interface, or the retrieval of information from the browser. However, session hijacking is not possible due to the httpOnly flag protecting session-related cookies.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Reflected cross-site scripting (XSS) vulnerability in the authentication endpoint where user-supplied input is not properly encoded before being rendered in the response page. Attackers can inject malicious JavaScript that executes in the victim's browser, enabling page redirection, UI manipulation, or sensitive data exfiltration via browser APIs.

MitigationImplement proper output encoding/escaping for all user-supplied data rendered in HTML context at the authentication endpoint. Apply context-appropriate encoding (HTML, URL, JavaScript) based on where the data is inserted into the page.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm WSO2 product installation
    Locate the WSO2 installation directory. For API Manager, look for the 'wso2am' folder or check for 'wso2server.sh' or 'wso2server.bat' script. For Identity Server, look for 'wso2is' folder or 'wso2server' script. Check for the presence of 'repository/components' directory containing the product binaries.
    Affected if The product is WSO2 API Manager 3.1.0, 3.2.0, 3.2.1, 4.0.0, or 4.1.0; OR WSO2 Identity Server 5.10.0 or 5.11.0
  2. Determine installed product version
    Open the 'repository/components/plugins' directory and locate the core JAR file (typically 'org.wso2.carbon.core_*.jar'). Alternatively, check the 'carbon.xml' configuration file in 'repository/conf' for the 'ServerVersion' property. You can also view the product splash page or check the 'product-version' in the server startup logs.
    Affected if The installed version matches exactly: 3.1.0, 3.2.0, 3.2.1, 4.0.0, or 4.1.0 for API Manager; or 5.10.0 or 5.11.0 for Identity Server
  3. Verify authentication endpoint is accessible
    Access the default authentication endpoint URL. For API Manager, this is typically 'https://<host>:9443/authenticationendpoint/login.do'. For Identity Server, it is typically 'https://<host>:9443/login.do'. Confirm the endpoint responds with a login page.
    Affected if The authentication endpoint is exposed and accessible, meaning user input can be submitted to this endpoint
  4. Check for XSS vulnerability in authentication endpoint
    Send a crafted request to the authentication endpoint with a test payload in the query parameters (such as '<script>alert(1)</script>') and inspect the response HTML to see if the payload is reflected without proper encoding. Use browser developer tools or a proxy to view the raw HTTP response.
    Affected if User-supplied input in authentication endpoint parameters is reflected in the response without HTML encoding (unescaped '<' and '>' characters visible in the page source)

You are affected if you have WSO2 API Manager (exact versions 3.1.0, 3.2.0, 3.2.1, 4.0.0, 4.1.0) or WSO2 Identity Server (exact versions 5.10.0, 5.11.0) installed AND the authentication endpoint is accessible and reflects user input without encoding.
