Deeper analysis
CVE-2023-3822 is a reflected cross-site scripting vulnerability (CWE-79) affecting the Pimcore open-source platform prior to version 10.6.4. The flaw resides in the web application code and carries a CVSS 3.1 score of 6.1, reflecting network attack vector, low attack complexity, no required privileges, and required user interaction with changed scope.
An unauthenticated remote attacker can craft a malicious URL containing a reflected script payload; when a victim user follows the link, the script executes in the context of the Pimcore application, enabling limited data exposure and modification within the victim’s session.
