Root Cause Analysis
The vulnerability stems from insecure XML parsing in the Performance Plugin. The ZDI-21-1313 advisory explicitly references the TaurusParser
class as containing the flaw. XXE vulnerabilities typically occur when XML parsers have DTD/external entity processing enabled. Since TaurusParser
is specifically called out in vulnerability details and no XML hardening measures are mentioned in advisories, we can conclude its parse()
method lacks proper security configurations like disabling XXE through DocumentBuilderFactory
security features.
