CVSS: 8.5EPSS: 0%CPEs: 2EXPL: 0CVE-2023-7080 – Arbitrary remote code execution within wrangler dev Workers sandbox
https://notcve.org/view.php?id=CVE-2023-7080
The V8 inspector intentionally allows arbitrary code execution within the Workers sandbox for debugging. wrangler dev would previously start an inspector server listening on all network interfaces. This would allow an attacker on the local network to connect to the inspector and run arbitrary code. Additionally, the inspector server did not validate Origin/Host headers, granting an attacker that can trick any user on the local network into opening a malicious website the ability to run code. If wrangler dev --remote was being used, an attacker could access production resources if they were bound to the worker. This issue was fixed in wrangler@3.19.0 and wrangler@2.20.2. Whilst wrangler dev's inspector server listens on local interfaces by default as of wrangler@3.16.0, an SSRF vulnerability in miniflare https://github.com/cloudflare/workers-sdk/security/advisories/GHSA-fwvg-2739-22v7 (CVE-2023-7078) allowed access from the local network until wrangler@3.18.0. wrangler@3.19.0 and wrangler@2.20.2 introduced validation for the Origin/Host headers. • https://github.com/cloudflare/workers-sdk/issues/4430 https://github.com/cloudflare/workers-sdk/pull/4437 https://github.com/cloudflare/workers-sdk/pull/4535 https://github.com/cloudflare/workers-sdk/pull/4550 https://github.com/cloudflare/workers-sdk/security/advisories/GHSA-f8mp-x433-5wpf • CWE-269: Improper Privilege Management •

https://notcve.org/view.php?id=CVE-2023-3348
The Wrangler command line tool (<=wrangler@3.1.0 or <=wrangler@2.20.1) was affected by a directory traversal vulnerability when running a local development server for Pages (wrangler pages dev command). This vulnerability enabled an attacker in the same network as the victim to connect to the local development server and access the victim's files present outside of the directory for the development server. • https://developers.cloudflare.com/workers/wrangler https://github.com/cloudflare/workers-sdk https://github.com/cloudflare/workers-sdk/security/advisories/GHSA-8c93-4hch-xgxp • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
