DescriptionCVE.org

Trivy is a security scanner. Prior to 0.72.0, plugin manifest metadata is used by pkg/plugin/manager.go to construct paths under ~/.trivy/plugins without confining plugin names to that root, allowing an attacker who persuades a user to install or run a malicious plugin to write the manifest and plugin binary to arbitrary user-writable paths, while plugins from the official Trivy plugin index are not affected. This issue is fixed in version 0.72.0.

AnalysisAI

Arbitrary file write in Trivy's plugin manager prior to version 0.72.0 allows a malicious plugin author to escape the confines of ~/.trivy/plugins and write files to any user-writable filesystem path. The flaw exists in pkg/plugin/manager.go, where plugin manifest metadata is used to construct file paths without enforcing directory confinement, enabling a path traversal (CWE-22) attack. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the victim user to install or run a Trivy plugin obtained from an untrusted source outside the official Trivy plugin index. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 6.8 (AV:L/AC:L/AT:N/PR:N/UI:A/VI:H/VA:H) accurately reflects that exploitation requires local execution and active user interaction, significantly constraining real-world attack surface compared to network-exploitable vulnerabilities. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade Trivy to version 0.72.0 or later, the vendor-released patch available at https://github.com/aquasecurity/trivy/releases/tag/v0.72.0 and confirmed by commit d4213d7735c74e57f06c02ccb39ebca67abc7959. … Detailed patch versions, workarounds, and compensating controls in full report.
