A cross-site scripting vulnerability has been discovered affecting Iframe Dialog and Media Embed packages. The vulnerability may trigger a JavaScript code after fulfilling special conditions: using one of the affected packages on a web page with missing proper Content Security Policy configuration; initializing the editor on an element and using an element other than `<textarea>` as a base; and destroying the editor instance. This vulnerability might affect a small percentage of integrators that depend on dynamic editor initialization/destroy mechanism.\n\nA fix is available in CKEditor4 version 4.21.0. In some rare cases, a security fix may be considered a breaking change. Starting from version 4.21.0, the Iframe Dialog plugin applies the `sandbox` attribute by default, which restricts JavaScript code execution in the iframe element. To change this behavior, configure the `config.iframe_attributes` option. Also starting from version 4.21.0, the Media Embed plugin regenerates the entire content of the embed widget by default. To change this behavior, configure the `config.embed_keepOriginalContent` option. Those who choose to enable either of the more permissive options or who cannot upgrade to a patched version should properly configure Content Security Policy to avoid any potential security issues that may arise from embedding iframe elements on their web page."}], "lastModified": "2024-11-21T07:55:04.157", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:ckeditor:ckeditor:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "0DFC29A5-004B-4815-AF02-37517672D3F1", "versionEndExcluding": "4.21.0", "versionStartIncluding": "4.0"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:fedoraproject:fedora:37:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E30D0E6F-4AE8-4284-8716-991DFA48CC5D"}, {"criteria": "cpe:2.3:o:fedoraproject:fedora:38:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "CC559B26-5DFC-4B7A-A27C-B77DE755DFF9"}, {"criteria": "cpe:2.3:o:fedoraproject:fedora:39:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B8EDB836-4E6A-4B71-B9B2-AA3E03E0F646"}], "operator": "OR"}]}], "sourceIdentifier": "[email protected]"}
