What is CVE-2020-13639?

A stored Cross-Site Scripting (XSS) vulnerability exists within the ECT Provider component of OutSystems, allowing an unauthenticated remote attacker to store malicious JavaScript content. When administrators view this harmful Feedback content, the embedded script executes in their browser's security context. This poses a significant risk, as it could lead to unauthorized actions or data exposure. The issue affects various versions of OutSystems but has been addressed in specific updates, including OutSystems 10.0.1005.2 and later. It is crucial for organizations using these platforms to implement the latest security updates to mitigate potential threats.
