Description Jon Moroney 2026-07-06 20:11:31 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 would reuse a previously created connection even when some mTLS config
related option had been changed that should have prohibited reuse.

libcurl keeps previously used connections in a connection pool for subsequent
transfers to reuse if one of them matches the setup. However, some TLS
settings related to client certificates were left out from the configuration
match checks, making them match too easily. In particular options related to
the private key.

Hello,

This CVE affects Davix on EPEL8 platform, as over there we bundle libcurl v7.69.0.

Can patch our Davix codebase once upstream patch backport is published for curl v7.69.0.

Cheers,
Mihai
