Vulnerabilities

  • CVE-2023-25456admin≤ 3.0.7

    WordPress Klaviyo Plugin <= 3.0.7 is vulnerable to Cross Site Scripting (XSS)

    Medium 4.8

The access label is read from the record's own text (e.g. “subscriber+”: subscriber and above). When the text names no role, CVSS decides between “login required” and “high privilege”; no role name is invented. “Needs a click”: the attack depends on a logged-in user following a link (CSRF, reflected XSS).
