Source record

Technical description

The SEO Plugin by Squirrly SEO plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 12.4.16. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to invoke privileged state-changing Squirrly cloud API operations, such as revoking the site's Google Search Console and Google Analytics integrations via `api/gsc/revoke` and `api/ga/revoke`, that are otherwise restricted to administrator-level users holding the `sq_manage_settings` capability.

CVE / CNA vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
