CVE-2026-25707Network attack vector

File overwrite via unsanitized repository metadata paths

Published Jun 29, 2026 · Updated Jun 29, 2026

Relative path traversal in SUSE libzypp before 17.38.10 allows remote attackers supplying a repository to overwrite system files. The YUM RepomdFileReader and susetags ContentFileReader accept metadata paths containing parent-directory segments and pass locations outside the repository cache to download processing. Exploitation requires the system to consume attacker-supplied repository metadata; chosen-file overwrites can interrupt services or enable privilege escalation.
