DEBIAN-CVE-2026-3784 PUBLISHED CVSS 6.5 MEDIUM

Record from OSV · Published March 11, 2026

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.
