+title: Possible Content Security Policy bypass in Action Dispatch
+date: 2024-12-10
+description: |
+  There is a possible Cross Site Scripting (XSS) vulnerability
+  in the `content_security_policy` helper in Action Pack.
+
+  ## Impact
+
+  Applications which set Content-Security-Policy (CSP) headers
+  dynamically from untrusted user input may be vulnerable to
+  carefully crafted inputs being able to inject new directives
+  into the CSP. This could lead to a bypass of the CSP and its
+  protection against XSS and other attacks.
+
+  ## Releases
+
+  The fixed releases are available at the normal locations.
+
+  ## Workarounds
+
+  Applications can avoid setting CSP headers dynamically from
+  untrusted input, or can validate/sanitize that input.
+
+  ## Credits
+
+  Thanks to [ryotak](https://hackerone.com/ryotak) for the report!
