{"id":"GHSA-gx8m-f3mp-fg99","aliases":["CVE-2024-35621"],"title":"formwork Cross-site scripting vulnerability in Markdown fields","titleSource":"OSV","descriptionSource":"OSV","declaredSeverity":"MODERATE","description":"### 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","severity":"medium","score":4.8,"published":"2024-05-28T16:54:31.000Z","modified":"2026-07-08T06:53:06.086Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"getformwork/formwork","sources":[{"name":"OSV · GHSA-gx8m-f3mp-fg99","url":"https://osv.dev/vulnerability/GHSA-gx8m-f3mp-fg99"}],"ranges":[{"events":[{"introduced":"0"},{"fixed":"1.13.0"}],"type":"ECOSYSTEM"}],"versions":["0.10.0","0.10.1","0.10.2","0.10.3","0.10.4","0.10.5","0.11.0","0.11.1","0.11.2","0.12.0","0.12.1","0.6.10","0.6.11","0.6.12","0.6.9","0.7.0","0.7.1","0.7.2","0.8.0","0.8.1","0.9.0","0.9.1","0.9.2","0.9.3","0.9.4","0.9.5","0.9.6","1.0.0","1.1.0","1.1.1","1.10.0","1.10.1","1.10.2","1.10.3","1.11.0","1.11.1","1.12.0","1.12.1","1.2.0","1.2.1","1.3.0","1.3.1","1.4.0","1.4.1","1.4.2","1.4.3","1.4.4","1.4.5","1.4.6","1.4.7","1.5.0","1.5.1","1.5.2","1.6.0","1.6.1","1.7.0","1.7.1","1.8.0","1.9.0","1.9.1"],"fixed":["1.13.0"]}],"sourceAffected":[],"references":["https://github.com/getformwork/formwork/security/advisories/GHSA-gx8m-f3mp-fg99","https://nvd.nist.gov/vuln/detail/CVE-2024-35621","https://github.com/getformwork/formwork/commit/2d92e6dbf99a9a49797947afbda0cdd4e56e11df","https://github.com/getformwork/formwork/commit/6adc302f5a294f2ffbbf1571dd4ffea6b7876723","https://github.com/getformwork/formwork"],"sources":[{"name":"OSV","id":"GHSA-gx8m-f3mp-fg99","modified":"2026-07-08T06:53:06.086285941Z","url":"https://osv.dev/vulnerability/GHSA-gx8m-f3mp-fg99"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","score":4.8}],"products":[],"remediation":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T22:15:33.378Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
