CVE-2026-76203 is a vulnerability in maalfer Pentestify versions 1.2.0 through 2.3.2 involving incorrect ordering of validation and canonicalization in the report theme CSS sanitizer. This flaw allows an authenticated user to craft CSS that forces outbound HTTP requests from other users' browsers, potentially exposing their IP address and User-Agent. The issue arises because CSS hex escapes can reconstruct the url() function, bypassing the sanitizer's blocklist.

Incorrect Behavior Order: Validate Before Canonicalize in the report theme CSS sanitizer in maalfer Pentestify 1.2.0 through 2.3.2 allows an authenticated user to force outbound HTTP requests from other users' browsers, disclosing their IP address and User-Agent, via CSS hex escapes that reconstruct the url() function and evade the sanitizer blocklist

A stored cross-site scripting (XSS) vulnerability exists in the user management component of maalfer Pentestify before version 1.1.1. An authenticated attacker can inject arbitrary JavaScript into the username field, which is improperly escaped before being embedded in an onclick attribute. This allows the injected script to execute in the browser of another authenticated user when they click the account deletion button for the affected user.

Cross-site Scripting in the Markdown renderer in maalfer Pentestify before 2.3.2 allows authenticated users to execute arbitrary JavaScript in the application origin via a Markdown link whose URL contains a double quote, which closes the anchor's href attribute because the renderer's sanitization step does not escape quotes

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.

Cross-site Scripting in the finding renderer in maalfer Pentestify before 2.3.1 allows authenticated users to execute arbitrary JavaScript in the application origin via HTML markup stored in a finding's severity field, which the frontend interpolates unescaped into class and style attributes when rendering the report.
