    CVE-2026-41463

    ProjeQtor versions 7.0 through 12.4.3 contain a ZipSlip path traversal vulnerability in the plugin upload functionality that allows authenticated attackers with upload permissions to write files outside the intended extraction directory by crafting ZIP archives with directory traversal sequences. Attackers can exploit unvalidated archive extraction to write a PHP webshell to a web-accessible directory and achieve remote code execution with the privileges of the web server process.
