{"schema":"threatline.record/2","record":{"id":"CVE-2026-76780","aliases":[],"summary":"BeyondSEO <= 1.3.6 - Missing Authorization to Authenticated (Contributor+) Limited Privilege Escalation","details":"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.","categories":["Unclassified"],"product":"BeyondSEO – AI SEO to Improve Rankings, Listings & Online Visibility","vendor":"rankingcoach","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-76780","source_modified_at":"2026-10-28T06:45:20.777Z","fetched_at":"2026-10-28T08:18:35.509402Z","product":"BeyondSEO – AI SEO to Improve Rankings, Listings & Online Visibility","vendor":"rankingcoach","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.3.6","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T06:45:20.777Z","modified_at":"2026-10-28T06:45:20.777Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-76780","fetched_at":"2026-10-28T08:18:35.509402Z","source_modified_at":"2026-10-28T06:45:20.777Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/dd4b2396-288f-45e6-b911-b017dc8d0526?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/beyondseo/tags/1.3.1/inc/Modules/ModuleBase/BaseModule.php#L249"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/beyondseo/tags/1.3.1/inc/Modules/ModuleLibrary/Links/RedirectManager/RedirectManager.php#L67"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/beyondseo/tags/1.3.1/inc/Modules/ModuleBase/BaseSubmoduleApi.php#L289"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/beyondseo/tags/1.3.1/inc/Modules/ModuleLibrary/Links/RedirectManager/RedirectManagerApi.php#L266"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/beyondseo/tags/1.3.1/inc/Modules/ModuleLibrary/Links/RedirectManager/RedirectManagerHooks.php#L51"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3722492%40beyondseo&new=3722492%40beyondseo"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-28T06:45:20.777Z","content_hash":"15beb57b4fa6a33fea5acde719a0868e7b92c6c2b485e5a336fbc335f082a0ec"}}
