--- type: Article title: Using Cross-domain images in WebGL and Chrome 13 description: After shaders were shown to leak the contents of GPU textures, the WebGL spec was tightened so Chrome 13 and Firefox 5 reject cross-domain media as textures, raising DOM_SECURITY_ERR. A new .crossOrigin attribute lets a site opt back in via CORS. With it set, a remote image no longer dirties the canvas origin-clean flag, so toDataURL and getImageData succeed. resource: "https://blog.chromium.org/2011/07/using-cross-domain-images-in-webgl-and.html" tags: [article, webseclist-reference, en, chromium-blog, cors, same-origin-policy, info-leak, side-channel, timing-attack, mitigation, vendor-advisory, owasp-a01-2021] generated: by: webseclist-refs/1 at: "2026-08-10T15:04:14+00:00" status: stable stale_after: 2027-08-10 sources: - id: original resource: "https://blog.chromium.org/2011/07/using-cross-domain-images-in-webgl-and.html" title: Using Cross-domain images in WebGL and Chrome 13 author: Eric Bidelman also_at: [] authors: - Eric Bidelman canonical_url: "" cited_by: - "2011.md:47" commit: "" content_sha256: 3db18a7bde239766c0e1e01823520d9c8a608d3b6ed0b83c51dcfcfa6e41b791 depth: full depth_reason: default kind: article language: en licence: unknown original_url: "https://blog.chromium.org/2011/07/using-cross-domain-images-in-webgl-and.html" published: "" publisher: Chromium Blog publisher_english: "" raw_sha256: d35827c963ef2d299db8b801aad56e7408b4e34b9ad7de646124260aa6311ab8 retrieved_from: "https://blog.chromium.org/2011/07/using-cross-domain-images-in-webgl-and.html" retrieved_kind: live retrieved_utc: "2026-08-10T15:04:14+00:00" slug: chromium-blog-using-cross-domain-images-webgl-chrome-13 snapshot: "" title_english: "" translation_file: "" translation_of: "" --- # Using Cross-domain images in WebGL and Chrome 13 **Using Cross-domain images in WebGL and Chrome 13** - Eric Bidelman, Chromium Blog. - Published: date not stated - Original: - Preserved from: https://blog.chromium.org/2011/07/using-cross-domain-images-in-webgl-and.html (live) on 2026-08-10 - Licence: unknown Rights remain with the original author and publisher.
