| Doc Text: |
A flaw was found in BuildKit. An attacker who provides a crafted build definition can cause a Denial of Service (DoS) by crashing the BuildKit daemon. This issue occurs when a build definition resolves metadata for the same Git source reference multiple times, triggering an unhandled panic. Consequently, the daemon stops unexpectedly, interrupting all active build operations.
