CVE-2025-32386
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 document.

CVE-2025-32387
A Helm contributor discovered that a specially crafted JSON Schema within a chart can lead to a stack overflow.
Impact
A JSON Schema file within a chart can be crafted with a deeply nested chain of references, leading to parser recursion that can exceed the stack size limit and trigger a stack overflow.
Patches
This issue has been resolved in Helm v3.17.3.
Workarounds
Ensure that the JSON Schema within any charts loaded by Helm does not have a large number of nested references. These JSON Schema files are larger than 10 MiB.

CVE-2025-53547
A Helm contributor discovered that a specially crafted
Chart.yamlfile along with a specially linkedChart.lockfile can lead to local code execution when dependencies are updated.Impact
Fields in a
Chart.yamlfile, that are carried over to aChart.lockfile when dependencies are updated and this file is written, can be crafted in a way that can cause execution if that same content were in a file that is executed (e.g., abash.rcfile or shell script). If theChart.lockfile is symlinked to one of these files updating dependencies will write the lock file content to the symlinked file. This can lead to unwanted execution. Helm warns of the symlinked file but did not stop execution due to symlinking.This affects when dependencies are updated. When using the
helmcommand this happens whenhelm dependency updateis run.helm dependency buildcan write a lock file when one does not exist but this vector requires one to already exist. This affects the Helm SDK when the downloaderManagerperforms an update.Patches
This issue has been resolved in Helm v3.18.4
Workarounds
Ensure the
Chart.lockfile in a chart is not a symlink prior to updating dependencies.For more information
Helm's security policy is spelled out in detail in our SECURITY document.
