CVE-2025-32387

Name of the Vulnerable Software and Affected Versions: Helm versions prior to 3.17.3

Description: 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. This issue was discovered by a Helm contributor.

Recommendations: For versions prior to 3.17.3, update to Helm v3.17.3 to resolve the issue. As a temporary workaround, ensure that the JSON Schema within any charts loaded by Helm does not have a large number of nested references, specifically avoiding files larger than 10 MiB.
