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."}],"source":{"advisory":"GHSA-vh5c-xwqv-cv9g","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T12:38:25.306Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/ckeditor/ckeditor4/security/advisories/GHSA-vh5c-xwqv-cv9g","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/ckeditor/ckeditor4/security/advisories/GHSA-vh5c-xwqv-cv9g"},{"name":"https://ckeditor.com/cke4/addon/embed","tags":["x_refsource_MISC","x_transferred"],"url":"https://ckeditor.com/cke4/addon/embed"},{"name":"https://ckeditor.com/cke4/addon/iframe","tags":["x_refsource_MISC","x_transferred"],"url":"https://ckeditor.com/cke4/addon/iframe"},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GWKG2VCPJNETVCDTXU4X6FQ2PO6XCNGN/","tags":["x_transferred"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/VCYKD3JZWWA3ESOZG4PHJJEXT4EYIUIQ/","tags":["x_transferred"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/L4ODGOW6PYVOXHQSMWJBOCE6DXWAI33W/","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-10-15T17:09:11.109854Z","id":"CVE-2023-28439","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-10-15T17:12:27.344Z"}}]}}
