That helper interpolated the value into a shell command executed via Ruby backticks without quoting or escaping.\n\nImpact: an administrator who manages users against an external/federated LDAP directory via `yast2 users` triggers root command execution the moment they view or edit that particular user's \"Password Settings\" tab. No \"join domain\" or trust setup is required, just browsing/editing one user entry.\n\nThis issue affects yast2-users through 5.0.8.","publishedAt":"2026-09-01T09:20:45.365Z","updatedAt":"2026-09-02T03:55:31.732Z","severity":{"score":8.6,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"suse"},"assigner":"suse","products":["SUSE yast2-users"],"affected":[{"vendor":"SUSE","product":"yast2-users","packageName":"yast2-users","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.0.8","versionType":"semver"}],"repo":"https://github.com/yast/yast-users"}],"references":["https://bugzilla.suse.com/show_bug.cgi?id=1272839"],"weaknesses":["CWE-78","CWE-1287"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/59xxx/CVE-2026-59680.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-59680","state":"PUBLISHED","datePublished":"2026-09-01T09:20:45.365Z","dateUpdated":"2026-09-02T03:55:31.732Z","assignerShortName":"suse","assignerOrgId":"404e59f5-483d-4b8a-8e7a-e67604dd8afb","dateReserved":"2026-07-06T11:59:28.119Z"},"containers":{"cna":{"title":"yast2-users: OS command injection via LDAP-supplied shadowLastChange/shadowExpire attribute","descriptions":[{"lang":"en","value":"An OS command injection vulnerability was found in yast2-users.
