What is langflow's Vulert package health score?

Vulert scores langflow 50/100, which reads as usable, but worth attention.

Is the latest version of langflow affected?

Yes. 1.14.0.dev2, the version you would install today, has 23 known vulnerabilities, and 23 has no published fix yet. Use an earlier unaffected release, or the workaround each vulnerability lists.

How many vulnerabilities does langflow have?

87 vulnerabilities are recorded for langflow in the PyPI ecosystem: 17 critical, 18 high, 7 medium and 4 low, plus 41 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 langflow vulnerabilities disclosed?

76 vulnerabilities were recorded for langflow in the last 12 months, and the oldest entry in this database dates to 10 Jun 2024. 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 langflow 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 langflow for upcoming vulnerabilities?

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