CVE-2026-54448 · Severity: high · CVSS 4 · Published 2026-06-25

Aqua Security Trivy is a security scanner used to find vulnerabilities and misconfigurations in software projects and container images. A flaw in how it handles Helm chart archives allows an attacker to provide a specially crafted file that, when scanned, consumes all available system memory. This results in a denial-of-service condition where the scanner crashes, potentially disrupting automated software delivery pipelines and incurring additional cloud infrastructure costs.

## Technical details

Trivy's custom tar unpacker utilized `io.ReadAll` without size limits when processing Helm chart (`.tgz`) entries. An attacker can exploit this by placing a malicious, highly-compressed archive in a location scanned by Trivy (such as a git repository or container image build context). When Trivy attempts to parse the archive during a configuration or filesystem scan, the unbounded memory allocation causes the operating system's Out-Of-Memory (OOM) killer to terminate the process. The vulnerability was addressed in version 0.71.0 by replacing the custom unpacker with the official Helm SDK, which enforces per-entry and total size limits.
