Last modified

CVE-2026-55092 is a high-severity vulnerability rated 7/10 on the CVSS scale. Trivy is a security scanner. Prior to 0.71.1, when Trivy downloads an OCI artifact, it uses the org.opencontainers.image.title annotation from the artifact manifest as the destination filename without validation. EPSS estimates a 0.33% chance of exploitation in the next 30 days.

Description

Trivy is a security scanner. Prior to 0.71.1, when Trivy downloads an OCI artifact, it uses the org.opencontainers.image.title annotation from the artifact manifest as the destination filename without validation. An attacker who can make Trivy fetch an attacker-controlled artifact can supply a crafted annotation that resolves to a path outside the intended destination, causing Trivy to write the layer content to an arbitrary location on the host filesystem. This vulnerability is fixed in 0.71.1.
