Wrangler · Wrangler · CVE-2023-3348
**Name of the Vulnerable Software and Affected Versions**
Wrangler versions 3.1.0 and earlier, Wrangler versions 2.20.1 and earlier
**Description**
The issue is related to a directory traversal vulnerability that occurs when running a local development server for Pages using the `wrangler pages dev` command. This vulnerability allows an attacker on the same network as the victim to connect to the local development server and access files outside of the development server directory.
**Recommendations**
For Wrangler versions 3.1.0 and earlier, update to a version later than 3.1.0 to resolve the issue.
For Wrangler versions 2.20.1 and earlier, update to a version later than 2.20.1 to resolve the issue.
As a temporary workaround, consider restricting access to the local development server to minimize the risk of exploitation.
