{"id":"CVE-2026-100149","summary":"WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons \u003c= 4.7.3 - Unauthenticated Sensitive Information Disclosure via HMAC Signature Collision (Missing Domain Separation) in HMAC Signature Domain-Separation Flaw in `/yamidoo/v1/customer`…","details":"The WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.7.3 via the 'x-yamidoo-signature (attacker-obtained via inline_js identify payload)' parameter. 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.","modified":"2026-10-05T02:30:18.441020691Z","published":"2026-10-03T05:29:17.935Z","database_specific":{"cna_assigner":"Wordfence","cwe_ids":["CWE-200"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100149.json"},"references":[{"type":"WEB","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"},{"type":"WEB","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"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/tags/4.7.3/includes/classes/class-wpzoom-ai-chat.php#L921"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e0c9026c-d83e-41ac-be3a-93a33c32c47b?source=cve"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100149.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-100149"},{"type":"FIX","url":"https://github.com/wpzoom/social-icons-widget-by-wpzoom/commit/351a873ac6c99fd8fb63115628a9d612427c3097"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wpzoom/social-icons-widget-by-wpzoom","events":[{"introduced":"0"},{"fixed":"351a873ac6c99fd8fb63115628a9d612427c3097"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"4.7.3"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["4.7.3","4.7.2","4.7.1","4.7.0","4.6.3","4.6.2","4.6.1","4.6.0","4.5.11","4.5.10","4.5.7","4.5.9","4.5.8","4.5.6","4.5.5","4.5.4","4.5.3","4.5.2","4.5.1","4.5.0","4.3.4","4.3.3","4.3.2","4.3.1","4.3.0","4.2.18","4.2.17","4.2.16","4.2.15","4.2.14","4.2.13","4.2.12","4.2.11","4.2.10","4.2.9","4.2.8","4.2.7","4.2.6","4.2.5","4.2.4","4.2.3","4.2.2","4.2.1","4.2.0","4.1.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-100149.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
