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.","published":"2026-09-19T03:17:14.000Z","lastModified":"2026-09-21T13:33:33.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},"cwe":["CWE-862"],"affected":[],"epss":{"score":0.00336,"percentile":0.2679,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.34%).
