CVE-2026-93003

NetX Duo Web HTTP server interprets request body content as HTTP header fields

Published Oct 20, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed
Description
The Web add-on's HTTP server searches the entire request packet for header fields instead of stopping at the end of the header section. A header field name placed in the request body is therefore reported to the server as though it were a header, which lets a client control request framing decisions it should not be able to reach.
