CVE-2026-102727
What it is
In Eclipse ThreadX NetX Duo versions 6.0 through 6.5.2.202603a, the FTP server accepts the first connection to a passive data port without checking that it comes from the client that requested passive mode. An unauthenticated network attacker who connects to the predictable port first receives the file an authenticated user downloads, or supplies the content of the file the user uploads.
