CVE-2026-19434Network attack vector

Stored XSS via unvalidated severity attribute

Published Aug 11, 2026 · Updated Aug 11, 2026

Stored cross-site scripting in Maalfer Pentestify before 2.3.1 allows remote authenticated users to execute JavaScript via a finding severity value. The FindingBase and FindingTemplateBase schemas store the severity string without validation, and js/app.js interpolates it unescaped into class and style attributes. Execution occurs when a report containing the crafted finding is opened in Edit or Preview, affecting the application origin without demonstrated session access or data exfiltration.
