## Technical details

This is a reflected or stored cross-site scripting (XSS) vulnerability in the Oracle Agile PLM Web Client component. The vulnerability is easily exploitable and requires no authentication, but does require user interaction—typically when an attacker tricks a user into clicking a malicious link. The attack is delivered via HTTP and exploits a lack of input validation or output encoding in the Web Client. Successful exploitation allows an attacker to read, modify, or delete data accessible through the victim's session, with potential scope change affecting other Oracle Supply Chain products. Patches are available from Oracle; users should apply the latest updates to version 9.3.6 or later.
