What the vulnerability does

01Description

Due to a regression introduced in version 3.83.0, a security header is no longer applied to certain user-uploaded content served from repositories. This may allow an authenticated attacker with repository upload privileges to exploit a stored cross-site scripting (XSS) vulnerability with user context.
