CVE-2026-93326

Crafted Git build source can bypass certain policy validation

Published Oct 5, 2026 CVSS 4.0 · 6 Medium EPSS < 1% KEV · Not listed
Description
A build step for a Git source, crafted in a specific way, can bypass some policy validation rules. A malicious build definition can make the repository look like it is coming from a different remote URL than it really is when Git clone is happening. If policy is doing more stricter validation, for example based on commit SHA, commit data, or signatures, then all these validations still apply correctly.

Remediation
