CVE-2026-19716 maalfer CVE debrief

Who should care

Security teams and administrators responsible for Pentestify installations should be aware of this medium-severity vulnerability. Although details are limited, the ability for authenticated attackers to inject JavaScript into other users' browser sessions poses a risk. Organizations using Pentestify versions prior to 1.1.1 should prioritize patching or applying compensating controls.

Technical summary

CVE-2026-19716 is a Stored Cross-site Scripting (CWE-79) vulnerability in the user management component of Pentestify. An authenticated attacker can inject arbitrary JavaScript into the browser session of another authenticated user by crafting a malicious username. The vulnerability arises because the frontend escapes usernames with escapeHTML() before using them in the onclick attribute of the account deletion button. However, browsers decode HTML entities in attribute values before the JavaScript engine parses them, allowing an attacker to inject JavaScript by including an encoded single quote (') in the username. This injected JavaScript executes when the victim clicks the delete button for that account.

Defensive priority

Authenticated attackers may inject JavaScript into the browser sessions of other users via crafted usernames in the user management component of Pentestify. Although exploit details are limited, defenders should prioritize patching and compensating controls for this medium-severity vulnerability.

Recommended defensive actions

• Apply patches or updates to Pentestify version 1.1.1 or later if available
• Implement input validation and output encoding for usernames and other user-supplied data
• Enforce Content Security Policy (CSP) to restrict script execution
• Monitor user management component interactions for suspicious activity
• Consider compensating controls like Web Application Firewalls (WAFs) to detect and prevent attacks

Evidence notes

The CVE and NVD entries provide basic details about the Stored Cross-site Scripting (CWE-79) vulnerability in Pentestify's user management component. The CVE description outlines that an authenticated attacker can execute arbitrary JavaScript in another user's browser via a crafted username. However, specific exploit details and potentially affected configurations remain unclear. Vendor remediation appears to be version 1.1.1 or later, but confirmation is needed.
