NVD Description

Note: Versions mentioned in the description apply only to the upstream cfme-gemset package and not the cfme-gemset package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In Secure Headers (RubyGem secure_headers), a directive injection vulnerability is present in versions before 3.9.0, 5.2.0, and 6.3.0. If user-supplied input was passed into append/override_content_security_policy_directives, a newline could be injected leading to limited header injection. Upon seeing a newline in the header, rails will silently create a new Content-Security-Policy header with the remaining value of the original string. It will continue to create new headers for each newline. This has been fixed in 6.3.0, 5.2.0, and 3.9.0.
