Limited header injection when using dynamic overrides with user input in RubyGems secure_headers

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.

RubyGem 注入漏洞

RubyGems是RubyGems（Rubygems）组织的一款Ruby程序包管理器。该产品主要用于发布和管理Ruby程序包。 RubyGem secure_headers 3.9.0之前版本、5.2.0之前版本和6.3.0之前版本中存在注入漏洞。该漏洞源于用户输入构造命令、数据结构或记录的操作过程中，网络系统或产品缺乏对用户输入数据的正确验证，未过滤或未正确过滤掉其中的特殊元素，导致系统或产品产生解析或解释方式错误。
