CVE-2026-25761Network attack vector

Workflow command execution via crafted filenames

Published Feb 9, 2026 · Updated Feb 9, 2026

Command injection in Super-Linter 6.0.0 through 8.3.0 allows remote attackers to execute commands through crafted pull-request filenames. The BuildFileList function passes git ls-tree filenames through sh -c and eval during repository file discovery without neutralizing shell syntax. Exploitation requires a workflow that runs the action on an attacker-controlled pull request without administrator approval; commands run as the workflow runner and can read exposed GITHUB_TOKEN values.
