Description Jon Moroney 2026-07-08 18:25:13 UTC
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 keeps previously used connections in a connection pool for subsequent
transfers to reuse if one of them matches the setup.

An easy handle that first uses default native CA trust can continue trusting
the native platform store after the application switches that same handle to
custom CA material for a later transfer.

Comment 1 Mihai Patrascoiu 2026-07-14 13:12:07 UTC
Hello,

The CVE-2026-11564 vulnerability impacts curl versions 8.17.0 --> 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
