{"id":"CVE-2026-100149","state":"PUBLISHED","title":"WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons <= 4.7.3 - Unauthenticated Sensitive Information Disclosure via HMAC Signature Collision (Missing Domain Separation) in HMAC Signature Domain-Separation Flaw in `/yamidoo/v1/customer`…","description":"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.","publishedAt":"2026-10-03T05:29:17.935Z","updatedAt":"2026-10-03T15:42:43.954Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["wpzoom WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons"],"affected":[{"vendor":"wpzoom","product":"WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.7.3","versionType":"semver"}]}],"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"],"weaknesses":["CWE-200"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/100xxx/CVE-2026-100149.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-100149","state":"PUBLISHED","datePublished":"2026-10-03T05:29:17.935Z","dateUpdated":"2026-10-03T15:42:43.954Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-25T11:42:58.288Z"},"containers":{"cna":{"title":"WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons <= 4.7.3 - Unauthenticated Sensitive Information Disclosure via HMAC Signature Collision (Missing Domain Separation) in HMAC Signature Domain-Separation Flaw in `/yamidoo/v1/customer`…","descriptions":[{"lang":"en","value":"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.
