PublishedThe 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.

Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
Risk history
Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.
When does an EPSS score appear as a change?
A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.
Advisory history
1 saved versionsSee how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.
How advisory history works
Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
