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.","state":0,"publishedAt":"2026-10-03T05:29:17.935+00:00","modifiedAt":"2026-10-03T15:42:43.954+00:00","affected":[{"ecosystem":"Vendor product","name":"WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wpzoom\",\n                    \"product\": \"WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"4.7.3\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/e0c9026c-d83e-41ac-be3a-93a33c32c47b?source=cve","https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/tags/4.7.3/includes/classes/class-wpzoom-ai-chat-customer.php#L82","https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/tags/4.7.3/includes/classes/class-wpzoom-ai-chat.php#L921","https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/tags/4.7.3/includes/classes/class-wpzoom-ai-chat-customer.php#L93","https://github.com/wpzoom/social-icons-widget-by-wpzoom/commit/351a873ac6c99fd8fb63115628a9d612427c3097"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100149","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100149","identifiers":["CVE-2026-100149"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
