    CVE-2026-4103

    Insufficient HTML sanitization in the Publisher Portal and Developer Portal allows untrusted user input to be rendered without proper encoding or neutralization. This enables the injection and execution of malicious JavaScript when affected API documents are viewed. Successful exploitation may result in the execution of malicious scripts within the user's browser context when viewing API documentation. Users with permissions to access the API documentation through these portals may be impacted, potentially allowing attackers to perform actions on behalf of the user, depending on their session privileges.
