# IBM Guardium Key Lifecycle Manager: weak cryptography leaks sensitive information locally

Link for people: https://infrastack.ai/live/CVE-2026-78537 (this .md is for agents)

IBM Guardium Key Lifecycle Manager versions 4.1 through 5.1 use a weak cryptographic algorithm. A local attacker can obtain sensitive information as a result.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Guardium Key Lifecycle Manager version against the affected range: 4.1, 4.1.1, 4.2, 4.2.1, 5.0, 5.1.
