CVE-2026-3784  (opens in a new tab)

How to fix?

Upgrade Echo:latest curl to version 7.88.1-10+deb12u15 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

curl would wrongly reuse an existing HTTP proxy connection doing CONNECT to a server, even if the new request uses different credentials for the HTTP proxy. The proper behavior is to create or use a separate connection.
