{"cve":"CVE-2024-38356","nvd":{"published":"2024-06-19T20:15:11.453","modified":"2026-06-17T07:39:59.097","status":"Deferred","description":"TinyMCE is an open source rich text editor. A cross-site scripting (XSS) vulnerability was discovered in TinyMCE’s content extraction code. When using the `noneditable_regexp` option, specially crafted HTML attributes containing malicious code were able to be executed when content was extracted from the editor. This vulnerability has been patched in TinyMCE 7.2.0, TinyMCE 6.8.4 and TinyMCE 5.11.0 LTS by ensuring that, when using the `noneditable_regexp` option, any content within an attribute is properly verified to match the configured regular expression before being added. Users are advised to upgrade. There are no known workarounds for this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/tinymce/tinymce/commit/5acb741665a98e83d62b91713c800abbff43b00d","https://github.com/tinymce/tinymce/security/advisories/GHSA-9hcv-j9pv-qmph","https://owasp.org/www-community/attacks/xss","https://www.tiny.cloud/docs/tinymce/6/6.8.4-release-notes/#overview","https://www.tiny.cloud/docs/tinymce/7/7.2-release-notes/#overview"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:52:00.836172422+00:00"},"epss":{"cve":"CVE-2024-38356","score":0.00529,"percentile":0.44784,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9hcv-j9pv-qmph","url":"https://osv.dev/vulnerability/GHSA-9hcv-j9pv-qmph","summary":"TinyMCE Cross-Site Scripting (XSS) vulnerability using noneditable_regexp option","modified":"2026-09-10T03:50:16.204200468Z","packages":[{"ecosystem":"npm","name":"tinymce","purl":"pkg:npm/tinymce","ranges":["<5.11.0"],"fixed":["5.11.0"]},{"ecosystem":"NuGet","name":"TinyMCE","purl":"pkg:nuget/TinyMCE","ranges":["<5.11.0"],"fixed":["5.11.0"]},{"ecosystem":"Packagist","name":"tinymce/tinymce","purl":"pkg:composer/tinymce/tinymce","ranges":["<5.11.0"],"fixed":["5.11.0"]},{"ecosystem":"npm","name":"tinymce","purl":"pkg:npm/tinymce","ranges":[">=6.0.0 <6.8.4"],"fixed":["6.8.4"]},{"ecosystem":"npm","name":"tinymce","purl":"pkg:npm/tinymce","ranges":[">=7.0.0 <7.2.0"],"fixed":["7.2.0"]},{"ecosystem":"NuGet","name":"TinyMCE","purl":"pkg:nuget/TinyMCE","ranges":[">=6.0.0 <6.8.4"],"fixed":["6.8.4"]},{"ecosystem":"NuGet","name":"TinyMCE","purl":"pkg:nuget/TinyMCE","ranges":[">=7.0.0 <7.2.0"],"fixed":["7.2.0"]},{"ecosystem":"Packagist","name":"tinymce/tinymce","purl":"pkg:composer/tinymce/tinymce","ranges":[">=6.0.0 <6.8.4"],"fixed":["6.8.4"]},{"ecosystem":"Packagist","name":"tinymce/tinymce","purl":"pkg:composer/tinymce/tinymce","ranges":[">=7.0.0 <7.2.0"],"fixed":["7.2.0"]},{"ecosystem":"PyPI","name":"django-tinymce","purl":"pkg:pypi/django-tinymce","ranges":["<4.1.0"],"fixed":["4.1.0"]}]},{"id":"PYSEC-2026-1301","url":"https://osv.dev/vulnerability/PYSEC-2026-1301","summary":"TinyMCE Cross-Site Scripting (XSS) vulnerability using noneditable_regexp option","modified":"2026-07-07T17:46:38.036836600Z","packages":[{"ecosystem":"PyPI","name":"django-tinymce","purl":"pkg:pypi/django-tinymce","ranges":["<4.1.0"],"fixed":["4.1.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
