This makes it possible for authenticated attackers, with subscriber-level access and above, to extract other users' email addresses, login names, and registration dates via the Member Directory's per-row user rebinding when attacker-controlled base64 payloads in the [pp-custom-html] shortcode invoke [profile-email], [profile-username], and [profile-date-registered]. When the WordPress users_can_register option is enabled, unauthenticated attackers can also exploit this vulnerability by supplying the split shortcode fragments through the plugin's own registration handler, which processes the reg_nickname and reg_bio fields without a nonce requirement.","categories":["Unclassified"],"product":"Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress","vendor":"properfraction","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92536","source_modified_at":"2026-10-03T15:42:46.795Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress","vendor":"properfraction","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.17.4","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00634,"percentile":0.49765,"score_date":"2026-10-23"},"published_at":"2026-10-03T03:25:43.360Z","modified_at":"2026-10-03T15:42:46.795Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92536","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-03T15:42:46.795Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92536","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/1340aeb3-12a0-4965-95db-45d753935812?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.17.4/src/ShortcodeParser/FrontendProfileTag.php#L140"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.17.4/src/ShortcodeParser/MemberDirectoryTag.php#L237"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.17.4/src/ShortcodeParser/Builder/GlobalShortcodes.php#L165"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.17.4/src/Themes/DragDrop/ProfileFieldListing.php#L184"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.17.4/src/Themes/DragDrop/MemberDirectoryListing.php#L145"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.17.4/src/Functions/GlobalFunctions.php#L1715"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.17.4/src/Classes/RegistrationAuth.php#L131"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.17.4/src/Classes/EditUserProfile.php#L342"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-03T15:36:12.995969Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-03T15:42:46.795Z","content_hash":"e39a1839bd5990c908fd99ea0d8c850f53efa9cc0849ded41f509ff5039c6537"}}
