CVE-2026-107174

MediumCVSS 6.4
Published: Updated: Translated: NVD NIST

Summary

A flaw was found in source-to-image where unpacking archive files fails to properly sanitize symbolic links pointing to absolute file paths. An attacker supplying a malicious builder image can embed links pointing outside the extraction directory. This bypasses sandbox boundaries, potentially leading to unauthorized information disclosure or file modification on the host system.

Risk Assessment

An attacker can bypass the sandbox and access or modify host files, potentially resulting in data leakage or compromise of system integrity.

Recommendation

Upgrade source-to-image to a patched version. Avoid using untrusted builder images and verify their origin.
