# Werkzeug Windows Path Boundary Disclosure Record

Date: 2026-06-15

Status: sanitized public disclosure record in the responsible-disclosure lane.

## Summary

This is the public accountability record for a Werkzeug disclosure thread that
passed the 14-day no-response review date under our responsible-disclosure
rules.

Technical details are withheld here. This record exists so the disclosure
timeline is visible without publishing a reproduction recipe, private
correspondence, or raw technical material.

## What Was Reported Privately

- Reported area: Werkzeug path handling on Windows.
- Reported class: Windows/NTFS alternate-stream boundary handling across
  Werkzeug path flows.
- Public status: no maintainer acknowledgement or routing response is visible in
  the receipt source used for this lane.

The private report is about a specific Windows path interpretation boundary and
an alternate-stream exposure concern. This public record does not include the
triggering path form, route shape, file names, logs, or reproduction packet.

## Public Evidence

## Evidence Boundary

The public evidence proves a disclosure record exists, identifies the reported
component and issue class, and records the no-response timing basis. It does not
publish the private email body, path form, route shape, raw logs, or technical
packet.

## Timeline

- First disclosure email sent: 2026-05-25.
- 14-day no-response review date: 2026-06-08.
- Published as a sanitized public disclosure record: 2026-06-15.

## What We Are Asking For

- Acknowledge receipt or point to the correct Pallets/Werkzeug handling route.
- State whether this is already known, fixed, duplicate, out of scope, or needs
  the private packet resent.
- If more time is needed, say so and the public record can note that engagement
  has started.

## Rules Applied

- The first disclosure email starts the review clock.
- If there is no acknowledgement or reply after 14 days, a sanitized public
  record may be published after review.
- More detailed technical disclosure still requires separate human review.
- Private technical material remains reserved for an authorized security
  responder.

## Limits

This public record establishes the disclosure timeline. Untrusted control is not
proven in this public record. Current-version behavior is not proven in this
public record. Maintainer validation, remediation status, final severity, and
affected-version scope are not proven in this public record. Private technical
material is retained for authorized responders.
