    Title
    MailerLite – Signup forms (official) <= 1.7.16 - Authenticated (Administrator+) Stored Cross-Site Scripting
    Summary
    The MailerLite – Signup forms (official) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form_description' and 'success_message' parameters in versions up to, and including, 1.7.16 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator access or higher, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

    CVE-2024-1386 (GCVE-0-2024-1386)

    Vulnerability from nvd – Published: 2024-05-02 16:52 – Updated: 2024-08-01 18:40
    VLAI
    Summary
    The MailerLite – Signup forms (official) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in versions 1.5.0 to 1.7.6 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

    Title
    MailerLite – Signup forms (official) <= 1.7.16 - Authenticated (Administrator+) Stored Cross-Site Scripting
    Summary
    The MailerLite – Signup forms (official) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form_description' and 'success_message' parameters in versions up to, and including, 1.7.16 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator access or higher, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

    Vulnerability from cvelistv5 – Published: 2024-05-02 16:52 – Updated: 2024-08-01 18:40
    VLAI
    Summary
    The MailerLite – Signup forms (official) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in versions 1.5.0 to 1.7.6 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
