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.

GHSA-mcj4-mphf-j9ff — Trivy has a path traversal via a crafted vulnerability database or other downloaded artifacts

Affected: Go: github.com/aquasecurity/trivy

## Summary

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.

## Affected configurations

Exploitation requires the attacker to direct Trivy at an attacker-controlled OCI artifact via one of the following inputs:

| Input | Used for | | --- | --- | | `--db-repository` flag, `TRIVY_DB_REPOSITORY` environment variable, or `db.repository` in `trivy.yaml` | Vulnerability database | | `--java-db-repository` flag, `TRIVY_JAVA_DB_REPOSITORY` environment variable, or `db.java-repository` in `trivy.yaml` | Java vulnerability database | | `--checks-bundle-repository` flag (and the deprecated `--policy-bundle-repository` alias), `TRIVY_CHECKS_BUNDLE_REPOSITORY` environment variable, or `misconfiguration.checks-bundle-repository` in `trivy.yaml` | Misconfiguration checks bundle | | Repository argument to `trivy module install <REPO>` | WASM module installation |

Realistic scenarios in which an attacker may influence these inputs include a copy-pasted command or documentation snippet pointing to an untrusted mirror, or a third-party mirror that turns out to be hostile.
