This is due to two compounding flaws: (1) the save-time sanitization filter `et_builder_sanitize_dynamic_content_fields()` only searches for dynamic content markers in the `@ET-DC@...@` format, but the rendering engine also supports a legacy JSON format that is silently converted at render time, completely bypassing the save-time filter, and (2) the `post_meta_key` resolver in `et_builder_filter_resolve_default_dynamic_content()` does not apply `wp_kses_post()` to the resolved meta value when `enable_html` is set to `on`, passing raw `get_post_meta()` output directly to the page. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."}],"title":"Divi <= 4.27.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via Dynamic Content (Legacy JSON Format) Shortcode","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/9384d32d-77a1-4794-aace-96f553302a3b?source=cve"},{"url":"https://www.divichangelog.com/divi-update/divi-4/version-4-27-7"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Osvaldo Noe Gonzalez Del Rio (Os)"}],"timeline":[{"time":"2026-03-10T16:31:59.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-09-01T14:46:50.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-03T18:18:52.234758Z","id":"CVE-2026-3851","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-03T18:19:07.157Z"}}]}}
