phpList/phplist3

phpList before 3.6.15 is vulnerable to Cross-Site Scripting (XSS) due to improper input sanitization in lt.php. The vulnerability is exploitable when the application dynamically references internal paths and processes untrusted input without escaping, allowing an attacker to inject malicious JavaScript.

phpList before 3.6.15 is vulnerable to Reflected Cross-Site Scripting (XSS) via the /lists/dl.php endpoint. An attacker can inject arbitrary JavaScript code by manipulating the id parameter, which is improperly sanitized.
