CVE-2026-54448: Aquasec Trivy

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

Trivy is a security scanner. Prior to 0.71.0, when Trivy scans a Helm chart archive (.tgz), its custom tar unpacker reads each entry with io.ReadAll(tr) and no size limit. An attacker who can place a malicious .tgz file in the scanned path can craft a small compressed archive that decompresses to gigabytes, causing the Trivy process to be killed by the OS OOM killer. This vulnerability is fixed in 0.71.0.

Affected products

• Aquasec Trivy: before 0.71.0 (fixed in 0.71.0)
