CVE-2026-86022: VNote external program argument injection

CVE-2026-86022 · Severity: high · CVSS 7 · Published 2026-10-13

VNote is a note-taking application that allows users to open notes with external programs of their choice. Prior to version 4.3.0, an attacker could create a note with a specially crafted filename containing quote characters to inject additional arguments into the configured external program. If that program supports command execution (such as vim), an attacker could achieve arbitrary code execution on the user's system.

Technologies: Vnotex vNote. Vendors: Vnotex.

Technical details

SessionConfig::ExternalProgram::fetchCommand wraps note paths in double quotes and substitutes them into a command string that QProcess::start reparses into arguments, allowing argument injection via quote characters in filenames on Linux and macOS. The vulnerability exists in both the automatic-path feature (viewareacontroller.cpp) and the Open With feature (notebooknodecontroller.cpp). An attacker-controlled double quote in a POSIX filename can terminate the quoted path and inject arguments to execute commands through programs like vim with the -c option.

Affected products

vnotex VNote before 4.3.0
