|

"details": "### Impact\nA [cross-site scripting (XSS)](https://owasp.org/www-community/attacks/xss/) vulnerability was discovered in TinyMCE’s content insertion code. This allowed `iframe` elements containing malicious code to execute when inserted into the editor. These `iframe` elements are restricted in their permissions by same-origin browser protections, but could still trigger operations such as downloading of malicious assets.\n\n### Fix\nTinyMCE 6.8.1 introduced a new `sandbox_iframes` boolean option which adds the `sandbox=\"\"` attribute to every `iframe` element by default when enabled. This will prevent cross-origin, and in special cases same-origin, XSS by embedded resources in `iframe` elements. From TinyMCE 7.0.0 onwards the default value of this option is `true`.\n\nIn TinyMCE 7.0.0 a new `sandbox_iframes_exclusions` option was also added, allowing a list of domains to be specified that should be excluded from having the `sandbox=\"\"` attribute applied when the `sandbox_iframes` option is enabled. By default, this option is set to an array of domains that are provided in embed code by popular websites. To sandbox `iframe` elements from every domain, set this option to `[]`.\n\n### Workarounds\nThe HTTP Content-Security-Policy (CSP) `frame-src` or `object-src` can be configured to restrict or block the loading of unauthorized URLS. Refer to the [TinyMCE Content Security Policy Guide](https://www.tiny.cloud/docs/tinymce/latest/tinymce-and-csp/).\n\n### References\n- [TinyMCE 6.8.1](https://www.tiny.cloud/docs/tinymce/6/6.8.1-release-notes/#new-convert_unsafe_embeds-option-that-controls-whether-object-and-embed-elements-will-be-converted-to-more-restrictive-alternatives-namely-img-for-image-mime-types-video-for-video-mime-types-audio-audio-mime-types-or-iframe-for-other-or-unspecified-mime-types)\n- [TinyMCE 7.0.0](https://www.tiny.cloud/docs/tinymce/7/7.0-release-notes/#sandbox_iframes-editor-option-is-now-defaulted-to-true)\n",

A SVG image could be loaded though an `object` or `embed` element and that image could potentially contain a XSS payload.\n\n### Fix\nTinyMCE 6.8.1 introduced a new `convert_unsafe_embeds` option to automatically convert `object` and `embed` elements respective of their `type` attribute. From TinyMCE 7.0.0 onwards, the `convert_unsafe_embeds` option is enabled by default.\n\n### Workarounds\nIf you are using TinyMCE 6.8.1 or higher, set `convert_unsafe_embeds` to true. For any earlier versions, a custom NodeFilter is recommended to remove or modify any `object` or `embed` elements. This can be added using the `editor.parser.addNodeFilter` and `editor.serializer.addNodeFilter` APIs.\n\n### Acknowledgements\nTiny Technologies would like to thank Toni Huttunen of [Fraktal Oy](https://www.fraktal.fi/) for discovering this vulnerability.\n\n### References\n- [TinyMCE 6.8.1](https://www.tiny.cloud/docs/tinymce/6/6.8.1-release-notes/#new-convert_unsafe_embeds-option-that-controls-whether-object-and-embed-elements-will-be-converted-to-more-restrictive-alternatives-namely-img-for-image-mime-types-video-for-video-mime-types-audio-audio-mime-types-or-iframe-for-other-or-unspecified-mime-types)\n- [TinyMCE 7.0.0](https://www.tiny.cloud/docs/tinymce/7/7.0-release-notes/#convert_unsafe_embeds-editor-option-is-now-defaulted-to-true)\n\n",
