Origin Trust Ladder

The Chrome 150 SVG filter restriction creates a trust hierarchy: same-origin content can be filtered freely, while cross-origin content is protected. This trust ladder ranks every origin type — same-origin, cross-origin, sandboxed, data:, srcdoc, null — and shows which filter types are allowed, which are blocked, and why.

Hover a row to see the reason for each ruling. The ladder shows the security principle: SVG filters with pixel-reading primitives (feDisplacementMap, feComposite) create information leakage across origin boundaries.
