CVE-2026-19434: CWE-79 Improper neutralization of input during web page generation ('cross-site scripting') in maalfer Pentestify
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.
AI Analysis
Technical Summary
This vulnerability arises from improper neutralization of input during web page generation (CWE-79) in maalfer Pentestify versions prior to 2.3.1. Authenticated users can exploit this by injecting HTML markup containing JavaScript into the severity field of a finding. The frontend then inserts this unescaped markup into class and style attributes in the report rendering process, enabling execution of arbitrary JavaScript within the application's origin context.
Potential Impact
Successful exploitation allows authenticated users to execute arbitrary JavaScript code in the context of the application, potentially leading to session hijacking, unauthorized actions, or data exposure within the application scope. The CVSS 4.0 base score is 5.1, indicating a medium severity impact with network attack vector, low attack complexity, and partial impact on integrity and availability.
Mitigation Recommendations
No official patch or remediation level has been confirmed yet. Users should upgrade to version 2.3.1 or later once available, as this version presumably addresses the vulnerability. Until then, restrict access to trusted authenticated users and monitor for suspicious activity related to report rendering. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
