{"id":"CVE-2025-12094","state":"PUBLISHED","title":"OOPSpam Anti-Spam: Spam Protection for WordPress Forms & Comments (No CAPTCHA) <= 1.2.53 - Unauthenticated IP Header Spoofing","description":"The OOPSpam Anti-Spam: Spam Protection for WordPress Forms & Comments (No CAPTCHA) plugin for WordPress is vulnerable to IP Header Spoofing in all versions up to, and including, 1.2.53. This is due to the plugin trusting client-controlled forwarded headers (such as CF-Connecting-IP, X-Forwarded-For, and others) without verifying that those headers originate from legitimate, trusted proxies. This makes it possible for unauthenticated attackers to spoof their IP address and bypass IP-based security controls, including blocked IP lists and rate limiting protections, by sending arbitrary HTTP headers with their requests.","publishedAt":"2025-10-31T08:25:55.153Z","updatedAt":"2026-04-08T17:17:07.369Z","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":["oopspam OOPSpam Anti-Spam: Spam Protection for WordPress Forms & Comments (No CAPTCHA)"],"affected":[{"vendor":"oopspam","product":"OOPSpam Anti-Spam: Spam Protection for WordPress Forms & Comments (No CAPTCHA)","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.2.53","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/b5137bc2-912b-4e25-966e-515e8d9fc21c?source=cve","https://plugins.trac.wordpress.org/browser/oopspam-anti-spam/tags/1.2.49/include/helpers.php#L268","https://plugins.trac.wordpress.org/changeset/3386104/oopspam-anti-spam/trunk/include/helpers.php"],"weaknesses":["CWE-693"],"ingestedAt":"2026-10-29T20:08:31.050Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/12xxx/CVE-2025-12094.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-12094","state":"PUBLISHED","datePublished":"2025-10-31T08:25:55.153Z","dateUpdated":"2026-04-08T17:17:07.369Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-10-22T19:21:34.626Z"},"containers":{"cna":{"title":"OOPSpam Anti-Spam: Spam Protection for WordPress Forms & Comments (No CAPTCHA) <= 1.2.53 - Unauthenticated IP Header Spoofing","descriptions":[{"lang":"en","value":"The OOPSpam Anti-Spam: Spam Protection for WordPress Forms & Comments (No CAPTCHA) plugin for WordPress is vulnerable to IP Header Spoofing in all versions up to, and including, 1.2.53.
