Changelog

1.5.0 (2026.02.21)

  • drop support for Python 3.8 and 3.9

  • add support for Python 3.13

  • migrate from setup.py to pyproject.toml configuration

  • fix doc building on read the docs

  • SECURITY FIX: Fix critical path traversal and extension bypass vulnerability (CVE pending, CVSS 9.8)

    • Apply secure_filename() to the name parameter to prevent path traversal attacks

    • Re-validate file extension after name override to prevent extension bypass

    • Add path containment check to ensure files are saved within the upload directory

    • Sanitize folder component when extracted from name parameter

    Impact: This vulnerability allowed remote attackers to write files to arbitrary locations on the filesystem and bypass extension restrictions, potentially leading to remote code execution via Server-Side Template Injection (SSTI) in Flask applications.

    Recommendation: All users should upgrade to this version immediately. Do not pass user-controlled input to the name parameter in older versions.
