Detailsinfo

A vulnerability was found in WSO2 Identity Server (the affected version is unknown). It has been declared as problematic. This vulnerability affects an unknown code of the component Ajax Processor. The manipulation with an unknown input leads to a cross-site request forgery vulnerability. The CWE definition for the vulnerability is CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. As an impact it is known to affect integrity. CVE summarizes:

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.

The advisory is available at security.docs.wso2.com. This vulnerability was named CVE-2025-13394 since 11/19/2025. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
