{"id":"CVE-2022-2540","state":"PUBLISHED","title":"Link Optimizer Lite <= 1.4.5 - Cross-Site Request Forgery to Cross-Site Scripting","description":"The Link Optimizer Lite plugin for WordPress is vulnerable to Cross-Site Request Forgery to Cross-Site Scripting in versions up to, and including 1.4.5. This is due to missing nonce validation on the admin_page function found in the ~/admin.php file. This makes it possible for unauthenticated attackers to modify the plugin's settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.","publishedAt":"2022-09-06T17:18:59.000Z","updatedAt":"2026-04-08T17:22:09.440Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["adambard Link Optimizer Lite"],"affected":[{"vendor":"adambard","product":"Link Optimizer Lite","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.4.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/ca64692b-b194-4ceb-975e-72e4041252f2?source=cve","https://plugins.trac.wordpress.org/browser/link-optimizer-lite/1.4.5/admin.php#L20","https://www.wordfence.com/vulnerability-advisories/#CVE-2022-2540"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T19:50:01.354Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/2xxx/CVE-2022-2540.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2022-2540","state":"PUBLISHED","datePublished":"2022-09-06T17:18:59.000Z","dateUpdated":"2026-04-08T17:22:09.440Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2022-07-26T00:00:00.000Z"},"containers":{"cna":{"title":"Link Optimizer Lite <= 1.4.5 - Cross-Site Request Forgery to Cross-Site Scripting","descriptions":[{"lang":"en","value":"The Link Optimizer Lite plugin for WordPress is vulnerable to Cross-Site Request Forgery to Cross-Site Scripting in versions up to, and including 1.4.5.
