Official Description
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.
Technical Analysis
CVE-2026-41463 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
