When decomposing a Source DataStream (SDS) file, the application does not properly validate relative file path attributes, leading to a path traversal vulnerability. An attacker can exploit this flaw by tricking a user or automated system into decomposing a crafted datastream containing directory traversal sequences. Successful exploitation allows unauthorized file creation or modification outside the intended target directory with the permissions of the executing process.","state":0,"publishedAt":"2026-10-21T19:42:54.174+00:00","modifiedAt":"2026-10-23T05:27:17.756+00:00","affected":[{"ecosystem":"https://catalog.redhat.com/software/containers/","name":"openscap-main","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Hardened Images\",\n                    \"collectionURL\": \"https://catalog.redhat.com/software/containers/\",\n                    \"packageName\": \"openscap-main\",\n                    \"defaultStatus\": \"affected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"1.4.5-2.1.hum1\",\n                            \"lessThan\": \"*\",\n                            \"versionType\": \"rpm\",\n                            \"status\": \"unaffected\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:/a:redhat:hummingbird:1\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"openscap","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 10\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"openscap\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:10\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"openscap","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 6\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"openscap\",\n                    \"defaultStatus\": \"unknown\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:6\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"openscap","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 7\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"openscap\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:7\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"openscap","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 8\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"openscap\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:8\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"openscap","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 9\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"openscap\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:9\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:L","score":6.1,"severity":"MEDIUM"}],"references":["https://access.redhat.com/errata/RHSA-2026:88330","https://access.redhat.com/security/cve/CVE-2026-85518","https://bugzilla.redhat.com/show_bug.cgi?id=2478522"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-85518","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-85518","identifiers":["CVE-2026-85518"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
