    JetFormBuilder < 3.6.5.2 - Unauthenticated Email Header Injection via Send Email Action

    CVE-2026-19859 (GCVE-0-2026-19859)

    Vulnerability from nvd – Published: 2026-09-06 09:36 – Updated: 2026-09-06 10:43

    Title
    JetFormBuilder < 3.6.5.2 - Unauthenticated Arbitrary Shortcode Execution via 'status' Parameter
    Summary
    The JetFormBuilder WordPress plugin before 3.6.5.2 does not sanitize a request parameter before rendering it as message content, allowing unauthenticated users to execute arbitrary shortcodes registered on the site on any page displaying a form. Escaping is applied to that content before a later shortcode-expansion pass rather than after it, so the escaping can be bypassed.

    CVE-2026-19859 (GCVE-0-2026-19859)

    Title
    JetFormBuilder < 3.6.5.2 - Unauthenticated Arbitrary Shortcode Execution via 'status' Parameter
    Summary
    The JetFormBuilder WordPress plugin before 3.6.5.2 does not sanitize a request parameter before rendering it as message content, allowing unauthenticated users to execute arbitrary shortcodes registered on the site on any page displaying a form. Escaping is applied to that content before a later shortcode-expansion pass rather than after it, so the escaping can be bypassed.
    Severity
    6.5 (Medium)
