CVE-2025-32386Network attack vector

Application termination via unbounded chart extraction

Published Apr 9, 2025 · Updated Apr 10, 2025

Resource exhaustion in Helm before 3.17.3 allows remote attackers to terminate the application via a crafted chart archive. LoadArchiveFiles copies decompressed tar entries into memory without per-file or total expanded-size limits, allowing a small archive to consume available memory. Exploitation requires a user or consuming SDK application to load the attacker-supplied chart, and the bounded consequence is process termination.
