What is CVE-2026-42881?

STIGQter, an open-source reimplementation of DISA's STIG Viewer, is susceptible to a local code execution vulnerability. Versions from 0.1.2 up to but not including 1.2.7 could allow an attacker to execute arbitrary code with the privileges of the user running the application. This can occur through user interaction, where the victim must open a crafted .stigqter file and trigger the 'Export HTML' action. The vulnerability underscores the importance of caution with user-uploaded files and highlights the need for secure coding practices to mitigate such risks.

Affected Version(s)

STIGQter >= 0.1.2, < 1.2.7
