Security

• CSP directive injection via sandbox, plugin-types, and report-to when given untrusted input — GHSA-rqq5-2gf9-4w4q. Reported by @tonghuaroot. The 2020 source-list scrub was not applied to the sandbox, plugin-types, and report-to directive builders, so caller-supplied values containing ;, \n, or \r were emitted verbatim into the Content-Security-Policy header and could inject arbitrary directives. All three builders now share the same scrub (replace ;, \n, \r with a space and Kernel.warn).
