{"id":"CVE-2025-30148","aliases":["GHSA-rhx4-hvx9-j387"],"url":"https://o3.security/vulnerability/CVE-2025-30148","summary":"Silverstripe Framework has a XSS vulnerability in HTML editor","details":"Silverstripe Framework is a PHP framework which powers the Silverstripe CMS. Prior to 5.3.23, bad actor with access to edit content in the CMS could send a specifically crafted encoded payload to the server, which could be used to inject a JavaScript payload on the front end of the site. The payload would be sanitized on the client-side, but server-side sanitization doesn't catch it. The server-side sanitization logic has been updated to sanitize against this attack. This vulnerability is fixed in 5.3.23.","published":"2025-04-10T13:02:22.415Z","modified":"2026-08-08T03:48:12.487849253Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"silverstripe/framework","fixedVersion":"5.3.23"}],"fix":{"url":"https://github.com/silverstripe/silverstripe-framework/commit/e99cfd62d160d145a76fcf9631e6b11226e42358","label":"silverstripe/silverstripe-framework@e99cfd6"},"references":[{"type":"WEB","url":"https://www.silverstripe.org/download/security-releases/cve-2025-30148"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/30xxx/CVE-2025-30148.json"},{"type":"ADVISORY","url":"https://github.com/silverstripe/silverstripe-framework/security/advisories/GHSA-rhx4-hvx9-j387"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-30148"},{"type":"FIX","url":"https://github.com/silverstripe/silverstripe-framework/commit/e99cfd62d160d145a76fcf9631e6b11226e42358"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:48:12.487849253Z"}}
