How this service works
Known security vulnerabilities for an open-source package from OSV (GitHub advisories, PyPA, RustSec, Go): id, CVE aliases, summary, severity, fixed versions, for all versions or one version. Ecosystems: npm, PyPI, Go, Maven, crates.io, RubyGems, NuGet, Packagist. Use before installing or upgrading.
Output
A list of vulnerability records from OSV, each containing: vulnerability ID, CVE aliases, a plain-English summary, severity rating, affected version ranges, and the versions in which the vulnerability was fixed. If a specific version is provided, results are filtered to vulnerabilities affecting that version only.
Example use cases
Pre-install security audit for npm
“I'm about to add 'axios' version 0.21.1 to my Node.js project — can you check if it has any known CVEs or security advisories in the OSV database?”
Python dependency vulnerability check
“We're using PyPI package 'Pillow' version 9.1.0 in production — please look up any known vulnerabilities for it so I know if we need to patch urgently.”
Rust crate safety review
“Can you check the crates.io package 'serde' for any known security vulnerabilities before we include it in our Rust project?”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/dev/vulns?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, up-to-date vulnerability data from OSV (covering GitHub advisories, PyPA, RustSec, and Go) for packages across npm, PyPI, Go, Maven, crates.io, RubyGems, NuGet, and Packagist — especially before installing or upgrading a dependency. Prefer it over generic web searches for security data because it returns machine-readable CVE IDs, severity, affected ranges, and fixed versions in a structured format directly from authoritative advisory databases.
Side effects
- Package not found in the specified ecosystem — returns empty results or 404
- Ecosystem parameter invalid or unsupported — may return an error or empty result
- Version string format mismatch — version not recognized, no results returned
- OSV upstream data unavailable — service timeout or 503
- Rate limiting or payment failure — 402 or 429 response
