CVE-2021-31414Network attack vector

Code execution via workspace-controlled linter path

Published Apr 16, 2021 · Updated Aug 3, 2024

Remote code execution in Laurent Tréguier RPM Specfile support in VSCode before 0.3.2 allows remote attackers to run arbitrary binaries. The extension reads rpmspec.rpmlintPath from workspace settings and launches that configured path when linting RPM spec files, so a repository can select an attacker-controlled executable. The crafted workspace must be loaded with the extension enabled and linting active; resulting code runs with the VS Code user's privileges.
