FKIE_CVE-2026-15155
Vulnerability from fkie_nvd - Published: 2026-07-11 07:16 - Updated: 2026-07-11 07:16
Severity
Summary
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.
