CVE-2026-93003NetX Duo Web HTTP server interprets request body content as HTTP header fields
Medium 6.9
In plain English
A medium-severity security flaw in Eclipse ThreadX - NetX Duo from Eclipse Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 26% of all known vulnerabilities).
Official 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.
