CVE-2026-22783Network attack vector

Authenticated arbitrary file deletion via mass assignment

Published Jan 12, 2026 · Updated Jan 12, 2026

Arbitrary file deletion in DFIR-IRIS iris-web before 2.4.24 allows remote authenticated users to delete filesystem paths. The datastore update route mass-assigns request fields into DSFileSchema, allowing file_local_name to be replaced, while datastore_delete_file resolves and unlinks that stored path without checking it remains under DATASTORE_PATH. An authenticated account must upload a datastore file, alter its stored local name, and invoke deletion, which can remove host files and interrupt service.
