What is CVE-2024-12139?

This vulnerability arises from the inadequate handling of error messages within WSO2 products, particularly related to URL parameters. The lack of proper sanitation and validation allows attackers to inject arbitrary content into these messages. As a result, users may be exposed to malicious error messages, leading to potential social engineering attacks. This manipulation can compromise sensitive information or trick users into performing harmful actions, such as credential theft or phishing.
