Hi, The following vulnerability was published for ruby-secure-headers. CVE-2020-5217[0]: | In Secure Headers (RubyGem secure_headers), a directive injection | vulnerability is present in versions before 3.8.0, 5.1.0, and 6.2.0. | If user-supplied input was passed into | append/override_content_security_policy_directives, a semicolon could | be injected leading to directive injection. This could be used to e.g. | override a script-src directive. Duplicate directives are ignored and | the first one wins. The directives in secure_headers are sorted | alphabetically so they pretty much all come before script-src. A | previously undefined directive would receive a value even if | SecureHeaders::OPT_OUT was supplied. The fixed versions will silently | convert the semicolons to spaces and emit a deprecation warning when | this happens. This will result in innocuous browser console messages | if being exploited/accidentally used. In future releases, we will | raise application errors resulting in 500s. Depending on what major | version you are using, the fixed versions are 6.2.0, 5.1.0, 3.8.0. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
