EPSS · scored 2026-10-27

Helm is a tool for managing Charts. A chart archive file can be crafted in a manner where it expands to be significantly larger uncompressed than compressed (e.g., >800x difference). When Helm loads this specially crafted chart, memory can be exhausted causing the application to terminate. This issue has been resolved in Helm v3.17.3.

  • GHSA-4hfp-h4cw-hj8pHelm Allows A Specially Crafted Chart Archive To Cause Out Of Memory Termination2025-04-10ghsa · osvUS

    A Helm contributor discovered that a specially crafted chart archive file can cause Helm to use all available memory and have an out of memory (OOM) termination. ### Impact A chart archive file can be crafted in a manner where it expands to be significantly larger uncompressed than compressed (e.g., >800x difference). When Helm loads this specially crafted chart, memory can be exhausted causing the application to terminate. ### Patches This issue has been resolved in Helm v3.17.3. ### Workarounds Ensure that any chart archive files being loaded by Helm do not contain files that are large enough to cause the Helm Client or SDK to use up available memory leading to a termination. ### For more information Helm's security policy is spelled out in detail in our [SECURITY](https://github.com/helm/community/blob/master/SECURITY.md) document. ### Credits Disclosed by Jakub Ciolek at AlphaSense.
