Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

OpenList versions before 4.2.3 are vulnerable to an arbitrary file write through the SimpleHttp offline-download tool. A user with the add-offline-download permission can supply a URL whose response sets a Content-Disposition filename containing path traversal sequences, causing the server to write or overwrite files the OpenList process can access. Upgrade to OpenList 4.2.3 or later, which is the listed fixed version.
