Summary
Kestra task inputFiles accepts traversal filenames for worker file writes
Details

Kestra is an open-source, event-driven orchestration platform. Prior to versions 1.3.19, 1.2.19, 1.1.19, and 1.0.43, Kestra task inputFiles writes rendered file names directly under the task working directory. When a flow forwards untrusted execution or webhook data into an inputFiles file name, a caller can use ../ path segments to create or overwrite files outside that task working directory on the worker filesystem. Versions 1.3.19, 1.2.19, 1.1.19, and 1.0.43 patch the issue.
