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. wp_kses_post does not strip the payload on save because the dangerous characters reside within shortcode attribute text between square brackets, which kses treats as plain text rather than HTML markup.","state":0,"publishedAt":"2026-10-28T06:45:13.36+00:00","modifiedAt":"2026-10-29T01:41:52.852+00:00","affected":[{"ecosystem":"Vendor product","name":"Avada (Fusion) Builder","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"themefusion\",\n                    \"product\": \"Avada (Fusion) Builder\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"3.16.2\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/650d346d-c30a-4ee1-ac50-6a264e181174?source=cve","https://avada.com/blog/version-7-16-3-security-update/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104729","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104729","identifiers":["CVE-2026-104729"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
