1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2026-23941)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to smuggle HTTP requests.

The vulnerability exists due to inconsistent interpretation of HTTP requests in inets httpd Content-Length parsing when processing requests with duplicate Content-Length headers that contain different values. A remote attacker can send a specially crafted request to smuggle HTTP requests.

Exploitation requires httpd to be deployed behind a reverse proxy, load balancer, or CDN that uses a different Content-Length resolution strategy, typically with persistent connections enabled.
