{"id":"CVE-2026-0722","state":"PUBLISHED","title":"Shield Security <= 21.0.8 - Cross-Site Request Forgery to SQL Injection","description":"The Shield Security plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 21.0.8. This is due to the plugin allowing nonce verification to be bypassed via user-supplied parameter in the 'isNonceVerifyRequired' function. This makes it possible for unauthenticated attackers to execute SQL injection attacks, extracting sensitive information from the database, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.","publishedAt":"2026-02-19T04:36:27.820Z","updatedAt":"2026-04-08T17:33:18.351Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["paultgoodchild Shield: Blocks Bots, Protects Users, and Prevents Security Breaches"],"affected":[{"vendor":"paultgoodchild","product":"Shield: Blocks Bots, Protects Users, and Prevents Security Breaches","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"21.0.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/f53d9579-56e9-41aa-b6b7-2472734ee719?source=cve","https://plugins.trac.wordpress.org/browser/wp-simple-firewall/tags/21.0.8/src/lib/src/ActionRouter/CaptureAjaxAction.php#L42","https://plugins.trac.wordpress.org/browser/wp-simple-firewall/tags/21.0.8/src/lib/src/ActionRouter/Actions/BaseAction.php#L125","https://plugins.trac.wordpress.org/browser/wp-simple-firewall/tags/21.0.8/src/lib/src/Tables/DataTables/LoadData/Traffic/BuildTrafficTableData.php#L114","https://research.cleantalk.org/cve-2026-0722/","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3439494%40wp-simple-firewall&new=3439494%40wp-simple-firewall&sfp_email=&sfph_mail="],"weaknesses":["CWE-89"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/0xxx/CVE-2026-0722.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-0722","state":"PUBLISHED","datePublished":"2026-02-19T04:36:27.820Z","dateUpdated":"2026-04-08T17:33:18.351Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-08T12:35:07.937Z"},"containers":{"cna":{"title":"Shield Security <= 21.0.8 - Cross-Site Request Forgery to SQL Injection","descriptions":[{"lang":"en","value":"The Shield Security plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 21.0.8.
