Because Node integration is enabled and context isolation is disabled in Obsidian's vault renderer, the injected script can call parent.require() to access Node APIs such as fs and child_process, enabling arbitrary operating system command execution when the victim opens the note and manually starts the presentation.","state":0,"publishedAt":"2026-10-08T16:27:08.486+00:00","modifiedAt":"2026-10-27T01:30:33.849+00:00","affected":[{"ecosystem":"Vendor product","name":"Obsidian Desktop","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"Obsidian\",\n                    \"product\": \"Obsidian Desktop\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"1.14.0\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.5,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://obsidian.md/changelog/2026-10-05-desktop-v1.14.4/","https://codeant.ai/security-research/from-markdown-to-a-shell-obsidian-desktop-rce","https://www.vulncheck.com/advisories/obsidian-desktop-rce-via-slides-plugin-markdown"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104077","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104077","identifiers":["CVE-2026-104077"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
