{"id":"CVE-2025-10745","state":"PUBLISHED","title":"Banhammer – Monitor Site Traffic, Block Bad Users and Bots <= 3.4.8 - Unauthenticated Protection Mechanism Bypass","description":"The Banhammer – Monitor Site Traffic, Block Bad Users and Bots plugin for WordPress is vulnerable to Blocking Bypass in all versions up to, and including, 3.4.8. This is due to a site-wide “secret key” being deterministically generated from a constant character set using md5() and base64_encode() and then stored in the `banhammer_secret_key` option. This makes it possible for unauthenticated attackers to bypass the plugin’s logging and blocking by appending a GET parameter named `banhammer-process_{SECRET}` where `{SECRET}` is the predictable value, thereby causing Banhammer to abort its protections for that request.","publishedAt":"2025-09-26T03:25:34.436Z","updatedAt":"2026-04-08T17:10:32.674Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["specialk Banhammer – Monitor Site Traffic, Block Bad Users and Bots"],"affected":[{"vendor":"specialk","product":"Banhammer – Monitor Site Traffic, Block Bad Users and Bots","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.4.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/97c46a13-6981-426f-b24a-c9820657042f?source=cve","https://plugins.trac.wordpress.org/browser/banhammer/trunk/inc/banhammer-functions.php#L336","https://plugins.trac.wordpress.org/browser/banhammer/trunk/inc/banhammer-core.php#L101","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3365979%40banhammer&new=3365979%40banhammer&sfp_email=&sfph_mail=","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3365087%40banhammer&new=3365087%40banhammer&sfp_email=&sfph_mail="],"weaknesses":["CWE-330"],"ingestedAt":"2026-10-29T20:08:20.985Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/10xxx/CVE-2025-10745.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-10745","state":"PUBLISHED","datePublished":"2025-09-26T03:25:34.436Z","dateUpdated":"2026-04-08T17:10:32.674Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-09-19T19:27:00.940Z"},"containers":{"cna":{"title":"Banhammer – Monitor Site Traffic, Block Bad Users and Bots <= 3.4.8 - Unauthenticated Protection Mechanism Bypass","descriptions":[{"lang":"en","value":"The Banhammer – Monitor Site Traffic, Block Bad Users and Bots plugin for WordPress is vulnerable to Blocking Bypass in all versions up to, and including, 3.4.8.
