    Vulnerabilities and exploitsOpen source package advisories

    GitHub publishes security advisories for open source packages in OSV format under a Creative Commons license. The database separates GitHub-reviewed advisories from unreviewed advisories imported from NVD.

    Known weaknesses

    Only GitHub-reviewed advisories include curated package names and affected version ranges. Unreviewed advisories are mostly NVD imports that lack package ecosystem data.

  • Metasploit Framework module metadata

    Vulnerabilities and exploitsExploit modules

    Rapid7 maintains Metasploit modules and a machine-readable metadata file inside the framework repository. The metadata lists module type, CVE references, targets, platforms, and disclosure dates.

    Known weaknesses

    Module coverage reflects Rapid7 and community priorities rather than all exploited vulnerabilities. Researchers should analyze the file db/modules_metadata_base.json instead of running any modules.

  • NVD CVE API 2.0

    Vulnerabilities and exploitsVulnerability database

    The National Vulnerability Database (NVD) API returns Common Vulnerabilities and Exposures (CVE) records with enrichment data. Enrichment adds Common Vulnerability Scoring System (CVSS) scores, Common Weakness Enumeration (CWE) types, and Common Platform Enumeration (CPE) names. The National Institute of Standards and Technology (NIST) also publishes bulk JSON feeds for offline analysis.

    Known weaknesses

    NVD has carried a growing enrichment backlog since early 2024 because CVE submissions rose sharply. Since April 15, 2026, NIST prioritizes Known Exploited Vulnerabilities (KEV), federal, and critical-software CVEs. Unenriched CVEs published before March 1, 2026 are now marked as Not Scheduled for enrichment. A free API key raises the request rate limit compared with anonymous access.

  • OpenSSF Malicious Packages

    Vulnerabilities and exploitsSoftware supply chain

    The Open Source Security Foundation (OpenSSF) collects reports of malicious packages found in open source registries. Reports use the OSV format and cover ecosystems such as npm and PyPI.

    Known weaknesses

    Records describe real malicious packages, so never install listed versions outside a sandbox. Coverage depends on contributing scanners and community reports rather than full registry audits.

    Vulnerabilities and exploitsOpen source package advisories

    The OSV.dev service aggregates open source vulnerability records in the shared Open Source Vulnerability (OSV) schema. It covers more than 40 package and operating system ecosystems with affected version ranges.

    Known weaknesses

    Each upstream source carries its own license, so attribution rules must be checked per ecosystem. Some records are converted from NVD and inherit its enrichment gaps and delays.

    Vulnerable code and software securityVulnerability fix commits

    CVEfixes automatically collects CVE records and their fix commits from open source repositories. It stores code before and after each change at file and method level in a relational database.

    Known weaknesses

    Fix commits often include changes unrelated to the vulnerability, which creates noisy function labels. The database file is large and is distributed through Zenodo rather than GitHub.

    Vulnerable code and software securitySecure code generation benchmark

    CyberSecEval from Meta measures whether large language models (LLMs) generate insecure code as coding assistants. It includes autocomplete and instruction tests scored by an insecure code detector.

    Known weaknesses

    Only the insecure code tests fit software security research on vulnerable code. Other suites in the repository measure attack compliance and prompt injection instead. Rule-based detection can flag safe code as insecure and inflate reported risk.
