CVE-2026-107929
Published:October 14, 2026
Updated:October 15, 2026
When "CURLOPT_INTERFACE" (or the command line tool's "--interface" option) is set with one of the documented prefixes ("if!", "host!", "ifhost!"), that binding is not part of the connection reuse key, so a later transfer asking for a different source can silently reuse an existing connection and go out from the earlier transfer's source address
