CVE-2026-15155 - Essential Addons for Elementor <= 6.6.10 - Authenticated (Contributor+) Account Takeover via Email Header Injection
CVE ID :CVE-2026-15155
Published : July 11, 2026, 7:16 a.m. | 3 hours, 30 minutes ago
Description :The Essential Addons for Elementor – Popular Elementor Templates & Widgets plugin for WordPress is vulnerable to Authenticated Account Takeover via Email Header Injection in all versions up to, and including, 6.6.10 This is due to insufficient server-side validation of a Login/Register widget setting used to construct outgoing email headers — the allowed-values restriction is enforced only in the client-side editor UI and not on the server, and the applied sanitization does not strip or encode CR/LF characters, allowing CRLF sequences stored in that setting to survive into raw mail headers. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject an additional Bcc header into the WordPress administrator's password-reset notification email, receive a copy of a valid administrator password-reset link, and achieve full administrator account takeover.
Severity: 8.8 | HIGH
