nektos — Vulnerabilities & Security Advisories 3

Nektos is a CLI tool for automating software development workflows, primarily used for GitHub Actions and other CI/CD pipelines. Historically, it has been susceptible to remote code execution vulnerabilities due to unsafe deserialization and command injection flaws, as well as privilege escalation issues through improper handling of environment variables. The project has addressed three CVEs to date, including RCE vulnerabilities in its YAML parsing and argument handling components. While no major public security incidents have been documented, the consistent presence of RCE flaws in its history suggests potential risks for organizations using the tool in production environments without proper input validation and sandboxing measures.
