## Technical details

A stored cross-site scripting (XSS) vulnerability exists in the Dev Studio component of Pega Platform versions 8.1.0 through 25.1.2. The flaw allows a high-privileged user with a developer role to inject malicious scripts into the user interface. These scripts are then executed in the browser of other users who view the affected component. Exploitation requires network access and user interaction from the victim. Pegasystems has released patches (24.2.4, 25.1.3) and specific hotfixes (HFIX-D578, HFIX-D579, HFIX-D580) to remediate the issue.
