{"id":"UBUNTU-CVE-2024-29203","details":"TinyMCE is an open source rich text editor. A cross-site scripting (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. This vulnerability is fixed in 6.8.1.","modified":"2025-10-24T05:09:09Z","published":"2024-03-26T14:15:00Z","upstream":["CVE-2024-29203"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-29203"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-29203"},{"type":"REPORT","url":"https://github.com/tinymce/tinymce/security/advisories/GHSA-438c-3975-5x3f"},{"type":"REPORT","url":"https://github.com/tinymce/tinymce/commit/bcdea2ad14e3c2cea40743fb48c63bba067ae6d1"}],"affected":[{"package":{"name":"tinymce","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/tinymce@3.4.8+dfsg0-1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.8+dfsg0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"tinymce","binary_version":"3.4.8+dfsg0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-29203.json"}},{"package":{"name":"tinymce","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/tinymce@3.4.8+dfsg0-2?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.8+dfsg0-2"],"ecosystem_specific":{"binaries":[{"binary_name":"tinymce","binary_version":"3.4.8+dfsg0-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-29203.json"}},{"package":{"name":"tinymce","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/tinymce@3.4.8+dfsg0-2?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.8+dfsg0-2"],"ecosystem_specific":{"binaries":[{"binary_name":"tinymce","binary_version":"3.4.8+dfsg0-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-29203.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
