Description Samuele Negrini 2026-07-30 14:28:26 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.

A relative path traversal bug problem when processing repository metadata in libzypp before 17.38.10 could be used by remote attackers supplying repositories to overwrite files on the system, leading to denial of service or privilege escalation.
Comment 1 Aoife Moloney 2026-08-17 15:42:50 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
