This is due to the plugin not performing any authentication and authorization checks. This makes it possible for unauthenticated attackers to extract sensitive data including customer names, email addresses, phone numbers, WhatsApp messages, complete geolocation data (IP addresses, city, country, ISP, coordinates), device fingerprinting information (browser, OS, screen resolution), and WordPress account credentials (user IDs, usernames, emails, names) for logged-in users who submit forms.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/chat-help/tags/3.1.1/src/Admin/Leads.php#L149","https://plugins.trac.wordpress.org/browser/chat-help/tags/3.1.1/src/Admin/Leads.php#L157","https://plugins.trac.wordpress.org/browser/chat-help/tags/3.1.1/src/Admin/Leads.php#L207","https://plugins.trac.wordpress.org/browser/chat-help/tags/3.1.1/src/Admin/Leads.php#L234","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3394141%40chat-help%2Ftrunk&old=3390862%40chat-help%2Ftrunk&sfp_email=&sfph_mail="],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-15291","score":0.0066,"percentile":0.51565,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
