CVE-2026-107174: Red Hat Openshift Serverless

Medium severity, CVSS 6.4. EPSS: 0.3% chance of exploitation in the next 30 days.

A flaw was found in source-to-image. When unpacking archive files, the application fails to properly sanitize symbolic links pointing to absolute file paths. An attacker who supplies a malicious builder image can exploit this vulnerability by embedding links pointing outside the extraction directory. This allows the attacker to bypass sandbox boundaries, potentially leading to unauthorized information disclosure or file modification on the host system.
