CVE-2026-27933: Unsanitized Filename Hash
Directly assigning an unsanitized hash/array lookup to a `filename` key can lead to Path Traversal (CWE-22) vulnerabilities when processed by file upload or storage libraries. Attackers can supply path traversal characters (e.g., `../`) to save or overwrite files outside the intended directory. Sanitize the user-supplied filename using `File.basename(...)`.
