CVE-2022-36055Network attack vector

Denial of service via unbounded array allocation

Published Sep 1, 2022 · Updated Apr 23, 2025

Uncontrolled resource consumption in Helm before 3.9.4 allows remote authenticated users to crash SDK applications via crafted value strings. The strvals parser expands attacker-controlled array indices into Go array structures without an allocation bound, exhausting memory and causing an unrecoverable panic. Exposure requires an SDK application to pass user-supplied strings to strvals; direct Helm CLI use only terminates that invocation and does not affect later runs.
