What is CVE-2026-19716?
CVE-2026-19716 is a medium-severity cross-site scripting vulnerability in maalfer Pentestify, published on 13 Aug 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
Stored Cross-site Scripting (CWE-79) in the user management component in maalfer Pentestify before 1.1.1 allows an authenticated attacker to execute arbitrary JavaScript in the browser of another authenticated user via a crafted username, because the frontend escapes the username with escapeHTML() before interpolating it into the onclick attribute of the account deletion button, but the browser HTML-decodes attribute values before the JavaScript engine parses the handler, allowing an encoded single quote (') to break out of the string literal and inject arbitrary JavaScript that executes when the victim clicks the delete button for that account.
Weakness: CWE-79
