{"id":"GHSA-4q66-g4mm-8rg5","aliases":[],"url":"https://o3.security/vulnerability/GHSA-4q66-g4mm-8rg5","summary":"Silverstripe has Cross-site Scripting (XSS) vulnerabilities inherited from TinyMCE","details":"TinyMCE 4.x is vulnerable to several XSS vectors, which had been patched in later versions. Two of these have been identified as affecting `silverstripe/admin`.\n\nOnly Silverstripe CMS 4 is affected by this issue. It's not possible to upgrade Silverstripe CMS 4 to use a more recent release of TinyMCE without introducing breaking changes. Instead, the security patches that shipped in later releases of TinyMCE have been backported to the TinyMCE version bundled in `silverstripe/admin`.\n\nSilverstripe CMS 5 is not affected by those vulnerabilities because it uses TinyMCE 6.\n\nYou can find more information about the underlying vulnerabilities in those GitHub security advisories:\n\n- [GHSA-5h9g-x5rv-25wg Cross-site scripting vulnerability in TinyMCE](https://github.com/advisories/GHSA-5h9g-x5rv-25wg)\n- [GHSA-w7jx-j77m-wp65 Cross-site scripting vulnerability in TinyMCE](https://github.com/advisories/GHSA-w7jx-j77m-wp65)","published":"2023-07-31T22:02:35Z","modified":"2024-12-02T05:44:34.311558Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"silverstripe/admin","fixedVersion":"1.13.6"}],"fix":{"url":"https://github.com/silverstripe/silverstripe-admin/commit/cafc1c4de58f1553b019dc2f8a62f835cabdbeb2","label":"silverstripe/silverstripe-admin@cafc1c4"},"references":[{"type":"WEB","url":"https://github.com/silverstripe/silverstripe-admin/security/advisories/GHSA-4q66-g4mm-8rg5"},{"type":"WEB","url":"https://github.com/silverstripe/silverstripe-admin/commit/cafc1c4de58f1553b019dc2f8a62f835cabdbeb2"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-5h9g-x5rv-25wg"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-w7jx-j77m-wp65"},{"type":"PACKAGE","url":"https://github.com/silverstripe/silverstripe-admin"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2024-12-02T05:44:34.311558Z"}}
