Snyk Open Source has added C/C++ security scanning for unmanaged dependencies, enabling development teams to find and fix known security vulnerabilities in their C/C++ open source library dependencies without needing manifests. The solution is developer-first, understanding the context and structure of C and C++ projects, leading to fewer false positives and less time spent correcting identifications manually. A new `--unmanaged` command-line option allows scanning for dependencies in source code without manifests. The vulnerability database is continuously improved by security and open source experts, providing recommended fixes and alerts for new vulnerabilities. To use the solution, install the Snyk CLI, authenticate with your account, and run the `snyk test --unmanaged` command to scan your project for vulnerabilities.
