Hi,

The following vulnerability was published for starlet.

CVE-2026-40561[0]:
| Starlet versions through 0.31 for Perl allows HTTP Request Smuggling
| via Improper Header Precedence.  Starlet incorrectly prioritizes
| "Content-Length" over "Transfer-Encoding: chunked" when both headers
| are present in an HTTP request. Per RFC 7230 3.3.3, Transfer-
| Encoding must take precedence.  An attacker could exploit this to
| smuggle malicious HTTP requests via a front-end reverse proxy.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
