CVE-2026-86415

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

Description The connection cache match function fails to consider the automatic client certificate option. This allows a cached Schannel connection that was already authenticated to be reused for a transfer redirected to a different origin, even if the automatic client certificate option was explicitly disabled for that specific transfer to prevent such an occurrence.

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