What scan4secrets is
scan4secrets is a free, MIT-licensed command-line tool for scanning source trees, running web apps, and CI logs for exposed credentials, code vulnerabilities, and misconfigurations. Its listed coverage is 416 rules: 193 for secrets and 223 for vulnerabilities or configuration problems. The SAST engine detects issues including injection, SSRF, XSS, weak cryptography, JWT flaws, and infrastructure configuration problems. For web scans, its crawler parses JavaScript source maps to extract endpoints and checks response headers. Authenticated DAST can use cookies, headers, and Burp or ZAP proxies; optional live verification probes vendor APIs to check whether discovered tokens are active. Reports can be exported as SARIF, JSON, JSONL, CSV, HTML, Excel, or PDF. Users can add secret and vulnerability rules by editing YAML files. The maker documents CI examples for pre-commit, GitHub Actions, GitLab CI, Jenkins, and Docker in CI. The tool supports Linux and Windows, and installation options include source, pipx, and Docker. Its architecture documentation lists a default maximum file size of 10 MB and maximum line length of 4096 characters. Secret values appear in full by default, so the maker recommends using --mask before sharing reports in artifact stores.
