Prior to 3.7.0 of the import-export module, an authenticated importer can submit a tar entry whose normalized destination targets a directory while bypassing the literal parent-path substring guard. Opening that directory as a write stream emits an unhandled filesystem error that can terminate the Node.js process; the source establishes this static primitive but not an end-to-end exploit or controlled arbitrary file read or write. This issue is fixed in version 3.7.0.","state":0,"publishedAt":"2026-10-20T17:15:01.932+00:00","modifiedAt":"2026-10-23T01:56:12.528+00:00","affected":[{"ecosystem":"Vendor product","name":"apostrophe","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"apostrophecms\",\n                    \"product\": \"apostrophe\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.33.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"import-export","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"@apostrophecms\",\n                    \"product\": \"import-export\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.7.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-97wv-p4xx-c7mg","https://github.com/apostrophecms/apostrophe/commit/9500b8b0e1d630d5e07fbb5fd2c25ed0943845ce","https://github.com/apostrophecms/apostrophe/commit/f84fd41cbf6c22eb8d0008fc9c25df1f7130b350","https://github.com/apostrophecms/apostrophe/releases/tag/@apostrophecms/import-export@3.7.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-113664","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-113664","identifiers":["CVE-2026-113664"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
