CVE-2025-13488

This may allow an authenticated attacker with repository upload privileges to exploit a stored cross-site scripting (XSS) vulnerability with user context.

MEDIUM 5.1EPSS 0.33%

Does this matter?

Lower severity and a low EPSS score (0.33%). Track it; it rarely justifies an emergency change on its own.

Description

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.
