{"cve":"CVE-2026-15660","nvd":{"published":"2026-09-19T03:17:13.717","modified":"2026-09-21T13:33:33.387","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-862"],"references":["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#L546","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","https://www.wordfence.com/threat-intel/vulnerabilities/id/3fd58af7-e8ef-4518-bed8-4e20c8e61db7?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-15660","score":0.00336,"percentile":0.27035,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
