A browser security standard restricting which scripts, styles, and network destinations a web page may load, set via HTTP headers or meta tags.
GoodBarber now serves on-device web content in its iOS apps from https://secure.internal, through a WKWebsiteDataStore proxy API added in iOS 17. A fixed name gives the company's token issuer one origin to allowlist, where the old loopback server needed a wildcard that matched any port on the phone.

Microsoft will allow only scripts from its own CDN domains during Entra ID browser sign-ins under a Content Security Policy enforced from mid-October 2026. Browser extensions and tools that inject code into the sign-in page will stop working as the rollout completes in late October.

MDN now lists the Trusted Types API as Baseline 2026, newly available. The JavaScript half only lets you sanitize; require-trusted-types-for is the part that makes an unsanitized assignment throw, and the sanitizer stays yours to write.

A per-request nonce met a statically prerendered page, and the browser refused every script it was sent. Six health signals, including a 3,500-test suite, reported fine.

Mixed content is the failure most likely to break a secure page, and it answers 200, so status-code checkers pass it. A Merlonix post argues the fix is protocol inspection, not more fetching.

A bank-statement converter enforcing connect-src 'none' skipped SheetJS and implemented the four files it needed. Then a green 26-test suite missed a CSP failure only the real page could show.
