Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Reflected XSS vulnerability in a template file within software authored by Gilles Dumas. The vulnerability allows attackers to inject malicious scripts through unsanitized user inputs that are reflected back in web pages without proper encoding, potentially enabling session hijacking or credential theft.

MitigationImplement proper input validation and output encoding for all user-supplied data in the template file to prevent script injection.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Gillesdumas Which Template File is installed
    Locate the software installation directory and identify if the 'Which Template File' application by Gilles Dumas is present on the system
    Affected if The software is installed and running
  2. Check installed version
    Examine the application's version information - check the main application file, about dialog, or version metadata to determine the installed version number
    Affected if The installed version is 4.9.0 or lower
  3. Locate template files in the installation
    Search the software directory for template files (commonly .php, .html, .tpl, or similar file extensions used for templating)
    Affected if Template files exist in the software installation
  4. Inspect template files for unsanitized user input reflection
    Review template files to identify any instances where user-supplied input (such as GET/POST parameters) is directly output without proper encoding or sanitization
    Affected if User input is being reflected in templates without encoding (e.g., direct output of request parameters)

The environment is affected if Gillesdumas Which Template File version 4.9.0 or lower is installed and template files contain unsanitized user input reflection
