Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

libcurl had a flaw that when instructed to clear proxy authentication
credentials which made it not do so, leaving the old credentials around to get
used for subsequent transfers that should not know nor use them.

Hello,

The CVE-2026-9079 vulnerability impacts curl versions 8.8.0 --> 8.20.0.
Davix embeds curl v7.69.0 for EPEL8, whereas for all other platforms it uses the system-provided curl.

This vulnerability does not impact Davix.
Closing.

Cheers,
Mihai
