Enterprise Architect is vulnerable to XML External Entity (XXE) injection in the XSLT Debugger feature. When a user loads a crafted XML file containing a `DOCTYPE` with an external DTD reference, the parser processes external entities, allowing an attacker to read arbitrary files from the victim's filesystem.

Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 17.1 but may also affect other versions.
