Release notes

3.1.5

This is the Werkzeug 3.1.5 security fix release, which fixes security issues and bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

• safe_join on Windows does not allow more special device names, regardless of extension or surrounding spaces. GHSA-87hc-h4r5-73f7

Greptile Overview

Greptile Overview

Greptile Summary

Updates werkzeug from 3.1.4 to 3.1.5, a security release fixing a Windows path traversal vulnerability in safe_join (GHSA-87hc-h4r5-73f7), multipart form parser boundary handling issues, and a DebuggedApplication initialization bug. Werkzeug is a dev dependency used by testing infrastructure.

Confidence Score: 5/5

• Safe to merge - routine security patch for dev dependency with no breaking changes
• This is a standard Dependabot security update that only modifies the poetry.lock file to bump werkzeug from 3.1.4 to 3.1.5. The update addresses security vulnerabilities and bug fixes without introducing breaking changes. Since werkzeug is only in the dev dependency group and not a runtime dependency, the impact is limited to the development and testing environment. The changes are automatically generated and verified by Dependabot.
• No files require special attention
