An unauthenticated attacker can delete arbitrary files on the server by manipulating the file_path parameter in the fusion_form_maybe_delete_files AJAX action. Deleting critical files like wp-config.php can lead to complete site takeover via reinstallation. This template detects the vulnerable version via homepage asset URL versioning (primary) and readme.txt Stable tag (fallback).\n  impact: |\n    An unauthenticated attacker can delete any file readable by the web server process, potentially leading to complete site compromise through wp-config.php deletion and WordPress reinstallation.\n  remediation:\n    Upgrade the Avada Builder (Fusion Builder) plugin to version 3.15.4 or later.\n  reference:\n    - https://www.wordfence.com/blog/2026/06/critical-unauthenticated-arbitrary-file-deletion-vulnerability-patched-in-avada-builder-wordpress-plugin/\n    - https://nvd.nist.gov/vuln/detail/CVE-2026-8713\n  classification:\n    cvss-metrics: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H\n    cvss-score: 9.1\n    cve-id: CVE-2026-8713\n    epss-score: 0.03007\n    epss-percentile: 0.87448\n    cwe-id: CWE-22\n  metadata:\n    verified: true\n    max-request: 1\n    shodan-query: http.component:\"WordPress\" http.component:\"Avada\"\n    fofa-query: body=\"fusion-builder\" && body=\"WordPress\"\n    product: fusion-builder\n    vendor: theme-fusion\n    framework: wordpress\n  tags: cve,cve2026,wordpress,wp-plugin,avada,fusion-builder,file-deletion,passive,vkev\n\nhttp:\n  - raw:\n      - |\n        GET / HTTP/1.1\n        Host: {{Hostname}}\n\n    matchers-condition: and\n    matchers:\n      - type: word\n        part: body\n        words:\n          - \"fusion-builder\"\n\n      - type: dsl\n        dsl:\n          - compare_versions(version, '<= 3.15.3')\n\n      - type: status\n        status:\n          - 200\n\n    extractors:\n      - type: regex\n        name: version\n        part: body\n        group: 1\n        regex:\n          - \"fusion-builder/assets/css/media/fullwidth[^\\\"']*\\\\?ver=([0-9]+\\\\.[0-9]+(?:\\\\.[0-9]+)?)\"\n          - \"id=['\\\"]fb-[^'\\\"]+['\\\"]\\\\s+href=['\\\"][^'\\\"]*\\\\?ver=([0-9]+\\\\.[0-9]+(?:\\\\.[0-9]+)?)['\\\"]\"\n        internal: true\n\n      - type: regex\n        name: detected_version\n        part: body\n        group: 1\n        regex:\n          - \"fusion-builder/assets/css/media/fullwidth[^\\\"']*\\\\?ver=([0-9]+\\\\.[0-9]+(?:\\\\.[0-9]+)?)\"\n          - \"id=['\\\"]fb-[^'\\\"]+['\\\"]\\\\s+href=['\\\"][^'\\\"]*\\\\?ver=([0-9]+\\\\.[0-9]+(?:\\\\.[0-9]+)?)['\\\"]\"\n# digest: 490a0046304402201579c2d8f253bf1db0a7229d0cc915adb4cc7c0ef2f903be1f83cabce60fb4610220066410c8d8cd2080da7476e16f93ddae25d112829cd90b0594ceee4c03c16077:922c64590222798bb761d5b6d8e72950"
