Description
TwsCachedXPathAPI in Convertigo versions before 8.3.11 did not restrict commons-jxpath functions, which could allow expression injection in contexts where an attacker can influence an evaluated XPath expression. Convertigo 8.3.11 fixes the issue by assigning an empty FunctionLibrary to JXPath contexts.
