This makes it possible for unauthenticated attackers to extract the full customer card — including name, WordPress user ID, order history, order totals, purchased products, payment method labels, and EDD Software Licensing license keys with status and activation counts — for any arbitrary victim email address on the site. Exploitation requires the attacker to register a WooCommerce customer or subscriber-level account with a crafted email address whose local part encodes the target timestamp and victim email, allowing the signature printed into the page HTML by inline_js() to pass verify_request() for an arbitrary victim; both the share_customer_data and identify_logged_in settings are enabled by default, so no non-default configuration is required.","categories":["Unclassified"],"product":"WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons","vendor":"wpzoom","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100149","source_modified_at":"2026-10-03T15:42:43.954Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons","vendor":"wpzoom","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.7.3","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00321,"percentile":0.2389,"score_date":"2026-10-23"},"published_at":"2026-10-03T05:29:17.935Z","modified_at":"2026-10-03T15:42:43.954Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100149","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-03T15:42:43.954Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100149","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/e0c9026c-d83e-41ac-be3a-93a33c32c47b?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/tags/4.7.3/includes/classes/class-wpzoom-ai-chat-customer.php#L82"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/tags/4.7.3/includes/classes/class-wpzoom-ai-chat.php#L921"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/tags/4.7.3/includes/classes/class-wpzoom-ai-chat-customer.php#L93"},{"source":"CVE List","url":"https://github.com/wpzoom/social-icons-widget-by-wpzoom/commit/351a873ac6c99fd8fb63115628a9d612427c3097"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-03T15:26:43.236916Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-03T15:42:43.954Z","content_hash":"bdf976c18d7821a5c2a0fb02af373ff66c504c1fef0446383824f7480a54b556"}}
