{"id":"CVE-2026-15660","state":"PUBLISHED","title":"SEO Booster <= 7.4.7 - Authenticated (Subscriber+) Missing Authorization to Arbitrary Options Modification via handle_oauth_callback()","description":"The SEO Booster plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 7.4.7. This is due to a missing capability check on the handle_oauth_callback() function which is hooked to admin_init and processes $_GET['access_token'] and $_GET['google_email'] without verifying the caller's role. This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the seobooster_access_token, seobooster_google_email, and seobooster_gsc_sites options and delete the seobooster_needs_reauth flag by visiting a crafted /wp-admin/ URL, disrupting the Google Search Console integration and injecting attacker-chosen data into site options via the attacker-supplied token that drives an outbound Google API request whose response is stored.","publishedAt":"2026-09-19T02:27:08.505Z","updatedAt":"2026-09-19T14:01:27.582Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["cleverplugins SEO Booster"],"affected":[{"vendor":"cleverplugins","product":"SEO Booster","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"7.4.7","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3fd58af7-e8ef-4518-bed8-4e20c8e61db7?source=cve","https://plugins.trac.wordpress.org/browser/seo-booster/tags/7.3.2/seo-booster.php#L546","https://plugins.trac.wordpress.org/browser/seo-booster/tags/7.3.2/seo-booster.php#L243","https://plugins.trac.wordpress.org/browser/seo-booster/tags/7.3.2/seo-booster.php#L547","https://plugins.trac.wordpress.org/changeset?reponame=&old=3665611%40seo-booster&new=3665611%40seo-booster"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15660.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15660","state":"PUBLISHED","datePublished":"2026-09-19T02:27:08.505Z","dateUpdated":"2026-09-19T14:01:27.582Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-13T20:07:22.067Z"},"containers":{"cna":{"title":"SEO Booster <= 7.4.7 - Authenticated (Subscriber+) Missing Authorization to Arbitrary Options Modification via handle_oauth_callback()","descriptions":[{"lang":"en","value":"The SEO Booster plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 7.4.7.
