Questions

About astro 6.0.0-beta.3

Is astro 6.0.0-beta.3 vulnerable?

Yes. 12 vulnerabilities in the Vulert database cover astro 6.0.0-beta.3: 2 critical, 2 high, 6 medium and 2 low. Each entry above names the fixed version to move to.

Is 6.0.0-beta.3 the latest release of astro?

No. 6.0.0-beta.3 was published 23 Jan 2026, and newer releases exist. Newer is not automatically safer — the version table on the package page shows what each release carries.

What does a malicious-package vulnerability mean?

It means the published package itself contained hostile code — a backdoor, a credential stealer or similar — rather than only a bug. Registries remove such packages once they are confirmed, so treat any application that resolved an affected version as compromised and rotate the credentials it could reach.

How do I monitor astro for upcoming vulnerabilities?

Upload the manifest or SBOM for your application at vulert.com/scanner and Vulert keeps checking the astro version you actually run against new disclosures, then alerts you when one affects it. There is no installation and no source-code access required.
