Multiple WSO2 products have been identified as vulnerable due to improper output encoding, a Stored Cross Site Scripting (XSS) attack can be carried out by an attacker injecting a malicious payload into the Registry feature of the Management Console.

A reflected XSS issue exists in the Management Console of several WSO2 products. This affects API Manager 2.2.0, 2.5.0, 2.6.0, 3.0.0, 3.1.0, 3.2.0, and 4.0.0; API Manager Analytics 2.2.0, 2.5.0, and 2.6.0; API Microgateway 2.2.0; Data Analytics Server 3.2.0; Enterprise Integrator 6.2.0, 6.3.0, 6.4.0, 6.5.0, and 6.6.0; IS as Key Manager 5.5.0, 5.6.0, 5.7.0, 5.9.0, and 5.10.0; Identity Server 5.5.0, 5.6.0, 5.7.0, 5.9.0, 5.10.0, and 5.11.0; Identity Server Analytics 5.5.0 and 5.6.0; and WSO2 Micro Integrator 1.0.0.

The Management Console in certain WSO2 products allows XXE attacks during EventReceiver updates. This affects API Manager through 3.0.0, API Manager Analytics 2.2.0 and 2.5.0, API Microgateway 2.2.0, Enterprise Integrator 6.2.0 and 6.3.0, and Identity Server Analytics through 5.6.0.

Apache Ant 1.1 to 1.9.14 and 1.10.0 to 1.10.7 uses the default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process.

In Apache Batik 1.x before 1.10, when deserializing subclass of `AbstractDocument`, the class takes a string from the inputStream as the class name which then use it to call the no-arg constructor of the class. Fix was to check the class type before calling newInstance in deserialization.
