AWS addresses relative path traversal flaw in ParallelCluster CLI log exports
What happened.Amazon Web Services published a security bulletin resolving a relative path traversal vulnerability affecting cluster log export commands in the AWS ParallelCluster command-line tool.
Why it matters.High-performance computing clusters rely on ParallelCluster to orchestrate massive distributed computational workloads across cloud resources. When command-line tooling allows directory traversal file writes, attackers tamper with orchestration scripts and elevate privileges. Cloud operations teams must upgrade local ParallelCluster installations to version 3.13.0 immediately.
