Hello, Could you help me understand how much control the embedding context has over an included iframe's CSP, please? Consider the following setup: - Embedding context: Content-Security-Policy: connect-src https://alice.com - https://alice.com iframe: Content-Security-Policy: connect-src https://bob.com Section 3.5 Policy applicability <https://www.w3.org/TR/CSP2/#which-policy-applies> states that for "Any resource included via iframe": > The policy of the embedding resource controls what may be embedded. > The embedded resource, however, is controlled by the policy delivered with the resource *Question: *Does this rule allow https://alice.com to connect to https://bob.com, even though the embedding context prohibits it? I could not find a "Policy applicability" section in the Editors draft <https://w3c.github.io/webappsec-csp/>. Was that removed intentionally? Thank you. Cheers, RouslanReceived on Friday, 16 September 2022 13:30:56 UTC
