CVSS v3.1

6.9

Medium

Base vector

AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:L/A:N

Name of the Vulnerable Software and Affected Versions Wrangler versions prior to 3.19.0

Description Sending specially crafted HTTP requests and inspector messages to Wrangler's dev server could result in any file on the user's computer being accessible over the local network. An attacker that could trick any user on the local network into opening a malicious website could also read any file.

Recommendations For versions prior to 3.19.0, update to version 3.19.0 or later. As a temporary workaround, configure Wrangler to listen on local interfaces instead with wrangler dev --ip 127.0.0.1. This removes the local network as an attack vector, but does not prevent an attack from visiting a malicious website.
