Description Cedric Buissart 2026-08-10 09:27:07 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 Fabio Valentini 2026-08-10 10:09:37 UTC
stgit links libcurl, but does not *include* it.
So this issue needs to be addressed in the curl package, and nothing can be done here.
