- →Detect HTTP requests containing multi-line Transfer-Encoding headers (i.e., a Transfer-Encoding header followed by a continuation line starting with whitespace/space, e.g., ' , chunked-false') — this is the smuggling vector exploited by CVE-2022-32215. ↗
- →Alert on HTTP responses where a single TCP stream yields two separate HTTP responses to one sent request — indicative of successful request smuggling (the server parsed one payload as two distinct requests). ↗
- →Flag Transfer-Encoding header values containing comma-separated tokens with a leading space on a continuation line (e.g., 'chunked\r\n , chunked-false'), as this pattern bypasses llhttp validation and enables HRS. ↗
- →Node.js versions v16.16.0 and v18.7.0 (and earlier in their respective lines: <v14.20.1, <v16.17.1, <v18.9.1) are confirmed vulnerable; flag traffic to/from Node.js HTTP servers running these versions. ↗
- ·CVE-2022-32215 was initially believed fixed but the fix was incomplete; the same exploit payload continued to work on Node v16.16.0 and v18.7.0. Ensure patching targets the corrected versions (≥v14.20.1, ≥v16.17.1, ≥v18.9.1) and not just any post-original-disclosure release. ↗
- ·The vulnerability is exploitable remotely over HTTP/HTTPS (CVSS up to 9.1 per Oracle); detection rules should cover both plaintext HTTP and TLS-terminated HTTP traffic proxied to Node.js backends. ↗
- ·Impact scope includes web cache poisoning, bypass of security layers, credential theft, and XSS — downstream effects may not be immediately visible at the Node.js layer and may require monitoring of upstream caches and proxies. ↗

The llhttp parser Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly handle multi-line Transfer-Encoding headers. This can lead to HTTP Request Smuggling (HRS).
A vulnerability was found in NodeJS due to the llhttp parser in the HTTP module incorrectly handling multi-line Transfer-Encoding headers. This issue can lead to HTTP Request Smuggling (HRS). This flaw allows a remote attacker to send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers, causing web cache poisoning, and conducting XSS attacks.

HTTP Request Smuggling Due to Incorrect Parsing of Multi-line Transfer-Encoding (improper fix for CVE-2022-32215)
**Summary:**
Due to an incomplete fix for CVE-2022-32215, the `llhttp` parser in the `http` module in Node v16.16.0 and 18.7.0 still does not correctly handle multi-line Transfer-Encoding headers. This can lead to HTTP Request Smuggling (HRS).

We have identified that the root issue of CVE-2022-32215 (that was [reported here](https://hackerone.com/reports/1501679)) was seemingly not fixed at all. Running the same exploit produces the same unwanted result. For the sake of brevity, I won't repeat the description, it can be seen in the [original issue](https://hackerone.com/reports/1501679).
