描述

### Impact A [cross-site scripting (XSS)](https://owasp.org/www-community/attacks/xss/) vulnerability was discovered in TinyMCE’s content extraction code. When using the `noneditable_regexp` option, specially crafted HTML attributes containing malicious code were able to be executed when content was extracted from the editor. ### Patches This vulnerability has been patched in TinyMCE 7.2.0, TinyMCE 6.8.4 and TinyMCE 5.11.0 LTS by ensuring that, when using the `noneditable_regexp` option, any content within an attribute is properly verified to match the configured regular expression before being added. ### Fix To avoid this vulnerability: * Upgrade to TinyMCE 7.2.0 or higher. * Upgrade to TinyMCE 6.8.4 or higher for TinyMCE 6.x. * Upgrade to TinyMCE 5.11.0 LTS or higher for TinyMCE 5.x (only available as part of commercial [long-term support](https://www.tiny.cloud/long-term-support/) contract). ### References * [TinyMCE 6.8.4](https://www.tiny.cloud/docs/tinymce/6/6.8.4-release-notes/#overview) * [TinyMCE 7.2.0](https://www.tiny.cloud/docs/tinymce/7/7.2-release-notes/#overview) ### For more information If you have any questions or comments about this advisory: * Email us at [[email protected]](mailto:[email protected]) * Open an issue in the [TinyMCE repo](https://github.com/tinymce/tinymce/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc)
