BeyondSEO <= 1.3.6 - Missing Authorization to Authenticated (Contributor+) Limited Privilege Escalation

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

The Beyondseo plugin for WordPress is vulnerable to unauthorized access in versions up to, and including, 1.3.6. This is due to the plugin permanently granting the 'rankingcoach_write_redirectManager' (and sibling rankingcoach_write_* module capabilities) to the Contributor role via BaseModule::defineCapabilities(), whose default role list includes 'contributor', combined with the module's REST endpoints (registered through BaseSubmoduleApi::registerRouteCreate/registerRouteEdit/registerRouteDelete) authorizing state-changing requests solely through checkPermissionsPost(), which only calls current_user_can('rankingcoach_write_<module>') and performs no admin capability, ownership, or additional nonce check inside the callback. This makes it possible for authenticated attackers, with Contributor-level access and above, to elevate their privileges to effectively that of an Administrator with respect to site-wide redirect management — creating, updating, or deleting 301/302 redirects that RedirectManagerHooks::handleRedirects() executes for every frontend visitor on template_redirect, allowing hijacking of arbitrary paths (including /checkout, /wp-login.
