Apache POI could allow a remote attacker to obtain sensitive information, caused by an XML external entity (XXE) error when processing XML data by tool XSSFExportToXml. By sending a specially-crafted document, a remote attacker could exploit this vulnerability to obtain sensitive information.

A cross-site scripting (XSS) vulnerability in the Color Dialog plugin for CKEditor 4.15.0 allows remote attackers to run arbitrary web script after persuading a user to copy and paste crafted HTML code into one of editor inputs.

It was possible to execute a ReDoS-type attack inside CKEditor 4 before 4.16 by persuading a victim to paste crafted URL-like text into the editor, and then press Enter or Space (in the Autolink plugin).
