{"id":"CVE-2026-53632","summary":"NTLMv2 hash disclosure via UNC path handling on Windows","details":"launch-editor allows users to open files with line numbers in editor from Node.js. Prior to 2.14.1, the launch-editor NPM package accesses arbitrary paths including Windows UNC paths. When a UNC path is opened, Windows automatically attempts NTLM authentication to the remote host, causing the user’s NTLMv2 password hash to be leaked to an attacker-controlled SMB server. This can result in credential compromise through offline hash cracking. This vulnerability is fixed in 2.14.1.","aliases":["GHSA-v6wh-96g9-6wx3"],"modified":"2026-08-12T03:30:25.302374417Z","published":"2026-06-22T15:54:09.240Z","related":["openSUSE-SU-2026:21448-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53632.json","unresolved_ranges":[{"extracted_events":[{"introduced":"8.0.0"},{"fixed":"8.0.16"},{"introduced":"7.0.0"},{"fixed":"7.3.5"},{"fixed":"6.4.3"},{"fixed":"0.1.24"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"GitHub_M","cwe_ids":["CWE-522","CWE-73"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53632.json"},{"type":"ADVISORY","url":"https://github.com/vitejs/launch-editor/security/advisories/GHSA-v6wh-96g9-6wx3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53632"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/vitejs/launch-editor","events":[{"introduced":"0"},{"fixed":"3f97c648307a70e7c930ba63f040e6ba8e72bc16"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.14.1"}],"source":"AFFECTED_FIELD"}}],"versions":["v2.14.0","v2.13.2","v2.13.1","v2.13.0","v2.12.0","v2.11.1","v2.11.0","v2.10.0","v2.9.1","v2.9.0","v2.8.2","v2.8.1","v2.8.0","v2.7.0","v2.6.1","v2.6.0","v2.5.0","v2.4.0","v2.3.0","v2.2.1","v2.2.0","v2.1.0","v2.0.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-53632.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H"}]}
