What is CVE-2026-41465?

The ProjeQtor application versions 7.0 to 12.4.3 has a vulnerability in its log file viewer located at dynamicDialog.php. This vulnerability allows authenticated attackers to exploit the logname parameter, which fails to properly validate input against directory traversal sequences. By injecting sequences such as '../', attackers can potentially access arbitrary log files on the web server's filesystem. This unauthorized file access could lead to exposure of sensitive information, posing a significant risk to data integrity and confidentiality.

Affected Version(s)

ProjeQtor 7.0 <= 12.4.3
