Summary

The vulnerability in the XLSX2CSV example of Apache POI prior to version 3.14 allows remote attackers to exploit XML External Entity processing. By submitting a crafted OpenXML document with an external entity declaration, attackers can read files arbitrarily from the server, posing a significant risk to sensitive data exposure. Proper validation and sanitization of XML input can mitigate this issue.
