CVE-2026-107929

Name of the Vulnerable Software and Affected Versions curl (affected versions not specified)

Description An issue exists where the connection reuse key does not include the binding when CURLOPT INTERFACE (or the --interface command line option) is configured with prefixes such as if!, host!, or ifhost!. This allows a subsequent transfer requesting a different source to silently reuse an existing connection, resulting in the traffic originating from the source address of the previous transfer.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
