Possible Content Security Policy bypass in Action Dispatch
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.
