Questions

About localstack

Is localstack safe to use?

Vulert records 6 vulnerabilities for localstack in PyPI: 1 critical, 1 high, 1 medium and 0 low, plus 3 not yet rated. 3 of them have no published fix yet, so those are the ones to avoid or mitigate.

What is localstack's Vulert package health score?

Vulert scores localstack 60/100, which reads as usable, but worth attention. The score weighs the vulnerability record (40), maintenance and release cadence (25), adoption from dependents and stars (20) and community signals such as the OpenSSF scorecard and forks (15). The current release has a vulnerability with no published fix, which caps this score.

Is the latest version of localstack affected?

Yes. 2026.8.2, the version you would install today, has 3 known vulnerabilities, and 3 has no published fix yet. Use an earlier unaffected release, or the workaround each vulnerability lists.

Which version of localstack should I use?

2026.8.2 is the version Vulert recommends for the affected releases. The version table above lists every release with the vulnerabilities recorded against it, so you can confirm the range you actually run.

How many vulnerabilities does localstack have?

6 vulnerabilities are recorded for localstack in the PyPI ecosystem: 1 critical, 1 high, 1 medium and 0 low, plus 3 not yet rated. The ledger on this page lists the same counts next to the date of the most recent disclosure.

How often are new localstack vulnerabilities disclosed?

0 vulnerabilities were recorded for localstack in the last 12 months, and the oldest entry in this database dates to 07 May 2021. Recency matters more than a lifetime total: it shows how actively new issues are being disclosed for the package you are considering.

Which versions of localstack are affected?

Each vulnerability on this page lists the affected version range and the fixed version to move to. Open the vulnerability for the version you actually run — fixes are specific to a release line, not to the package as a whole.

How do I monitor localstack for upcoming vulnerabilities?

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