Description Martin Prpič 2015-12-15 15:34:57 UTC 
In certain configurations, low privilege users were able to create e.g. HTML files in workspaces and archived artifacts that could result in XSS when accessed by other users. Jenkins now sends Content-Security-Policy headers that enables sandboxing and prohibits script execution by default.

This could allow low-privilege users to perform limited XSS in certain configurations.
