             Summary: Setting child-src does not update frame-src after initial assignment
                 Key: WICKET-6813
                 URL: https://issues.apache.org/jira/browse/WICKET-6813
             Project: Wicket
          Issue Type: Bug
          Components: wicket-core
    Affects Versions: 9.0.0, 9.0.0-M5
            Reporter: Mark Snijder


When configuring CHILD_SRC Wicket also configures FRAME_SRC ([CSPHeaderConfiguration.doAddDirective|https://github.com/apache/wicket/blob/bef3facb3b240f60a3455f257eaf1b9db81a9e29/wicket-core/src/main/java/org/apache/wicket/csp/CSPHeaderConfiguration.java#L310]) however it only does this when FRAME_SRC is not set.

Since _unsafeInline()_ sets CHILD_SRC to 'self', adding other CHILD_SRC directive values will not update the FRAME_SRC value anymore. The CSP settings in the code below causes a _Refused to frame 'https://docs.google.com/' because it violates the following Content Security Policy directive: "frame-src 'self'"._ error.
{code:java}
 getCspSettings().blocking()
	.unsafeInline()
	.add(CSPDirective.SCRIPT_SRC, "https://apis.google.com/")
	.add(CSPDirective.CHILD_SRC, "https://docs.google.com/");
{code}
A workaround is to add FRAME_SRC yourself manually to the code above (_.add(CSPDirective.FRAME_SRC, "https://docs.google.com/")_) but I would have expected the code to work without adding this.
