CVE-2026-19434 · Severity: info · CVSS 6.5 · Published 2026-08-11

Pentestify is a pentest report generation and management application used by security professionals to document and share findings with clients. An authenticated user can inject malicious JavaScript code through a finding's severity field, which is then executed in the browsers of anyone viewing the report. This allows attackers to steal session cookies, deface reports, or redirect users to malicious sites.

## Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in the finding renderer component. The backend accepted the severity field without validation, and the frontend interpolated it unescaped into HTML class and style attributes (e.g., `severity-<x>` and `var(--severity-<x>)`). An authenticated attacker could break the attribute boundary using `">` and inject an `<img onerror>` tag or similar payload to execute arbitrary JavaScript in the context of the application. The fix, released in v2.3.2, implements a whitelist of permitted severity values (crit, high, med, low, info) on both backend and frontend, and sanitizes output in all rendering sinks.
