{"id":"CVE-2024-35621","aliases":["GHSA-gx8m-f3mp-fg99"],"url":"https://o3.security/vulnerability/CVE-2024-35621","summary":"formwork Cross-site scripting vulnerability in Markdown fields","details":"### Impact\nUsers with access to the administration panel with page editing permissions could insert `<script>` tags in markdown fields, which are exposed on the publicly accessible site pages, leading to potential XSS injections.\n\n### Patches\n\n- [**Formwork 1.13.0**](https://github.com/getformwork/formwork/releases/tag/1.13.0) has been released with a patch that solves this vulnerability. Now the system config option `content.safe_mode` (enabled by default) controls whether HTML tags and potentially dangerous links are escaped. This is configurable as in some cases more flexibility should be given. Panel users should be only a controlled group of editors, which cannot enable the option by themselves, and not a generic group. This mitigates the chance of introducing vulnerabilities.\n- [**Formwork 2.x** (6adc302)](https://github.com/getformwork/formwork/commit/6adc302f5a294f2ffbbf1571dd4ffea6b7876723) adds a similar `content.safeMode` system option. Like Formwork 1.13.0, by default HTML tags and dangerous link are escaped. Even if enabled by an administrator, however, `<script>` and other dangerous tags are still converted to text, but secure tags are allowed.\n\n### References\nhttps://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-35621\n","published":"2024-05-28T15:40:26.625Z","modified":"2026-08-12T03:51:38.055477090Z","cvss":{"score":4.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"getformwork/formwork","fixedVersion":"1.13.0"}],"fix":{"url":"https://github.com/getformwork/formwork/commit/2d92e6dbf99a9a49797947afbda0cdd4e56e11df","label":"getformwork/formwork@2d92e6d"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/35xxx/CVE-2024-35621.json"},{"type":"ADVISORY","url":"https://github.com/getformwork/formwork/security/advisories/GHSA-gx8m-f3mp-fg99"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-35621"},{"type":"WEB","url":"https://github.com/getformwork/formwork/commit/2d92e6dbf99a9a49797947afbda0cdd4e56e11df"},{"type":"WEB","url":"https://github.com/getformwork/formwork/commit/6adc302f5a294f2ffbbf1571dd4ffea6b7876723"},{"type":"PACKAGE","url":"https://github.com/getformwork/formwork"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:38.055477090Z"}}
