A Cascading Style Sheets (CSS) injection vulnerability in Swagger UI before 3.23.11 allows attackers to use the Relative Path Overwrite (RPO) technique to perform CSS-based input field value exfiltration, such as exfiltration of a CSRF token value. In other words, this product intentionally allows the embedding of untrusted JSON data from remote servers, but it was not previously known that <style>@import within the JSON data was a functional attack method.

A flaw was found in dom4j library. By using the default SaxReader() provided by Dom4J, external DTDs and External Entities are allowed, resulting in a possible XXE.

A vulnerability was found in xstream API version 1.4.10, if the security framework has not been initialized, it may allow a remote attacker to run arbitrary shell commands by manipulating the processed input stream when unmarshaling XML or any supported format. e.g. JSON. This a regression of CVE-2013-7285 fixed in 1.4.7 (fixed) as of BPMS 6.0.1, the regression was introduced with xstream-1.4.10 implemented in RHPAM.
