Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Flask-Reuploaded provides file uploads for Flask. A critical path traversal and extension bypass
 vulnerability in versions prior to 1.5.0 allows remote attackers to achieve arbitrary file write and
 remote code execution through Server-Side Template Injection (SSTI). Flask-Reuploaded has been patched in
 version 1.5.0. Some workarounds are available. Do not pass user input to the `name` parameter, use auto-
 generated filenames only, and implement strict input validation if `name` must be used. (CVE-2026-27641)
