Last modified
CVE-2020-15171 is a medium-severity vulnerability rated 6.6/10 on the CVSS scale. In XWiki before versions 11.10.5 or 12.2.1, any user with SCRIPT right (EDIT right before XWiki 7.4) can gain access to the application server Servlet context which contains tools allowing to instantiate arbitrary Java objects and invoke methods that may lead to arbitrary code execution. The only workaround is to give SCRIPT right only to trusted users.. EPSS estimates a 1.34% chance of exploitation in the next 30 days.
