{"apiVersion":"1.0","identifier":"CVE-2026-63667","description":"ApostropheCMS is an open-source Node.js content management system. Prior to 3.6.2, the import-export module in packages/import-export/lib/formats/gzip.js constructs an attachment source path from the attacker-controlled _id, name, and extension fields in aposAttachments.json without ensuring that the resolved path remains under the extracted attachments directory, allowing an authenticated contributor to import a crafted archive, read a host file with an allowed extension, and publish the copied file at an unauthenticated uploads URL. This issue is fixed in version 3.6.2.","publishedAt":"2026-08-17T20:16:44","lastModifiedAt":"2026-08-17T20:16:44","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-63667","cvssScore":6.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","epssProbability":0.00341,"riskScore":0.67,"affectedProduct":"ApostropheCMS","affectedVersions":"<3.6.2","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-63667","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-63667","en":"https://www.redsauce.net/en/cves/CVE-2026-63667","fr":"https://www.redsauce.net/fr/cves/CVE-2026-63667","pt":"https://www.redsauce.net/pt/cves/CVE-2026-63667","de":"https://www.redsauce.net/de/cves/CVE-2026-63667","sk":"https://www.redsauce.net/sk/cves/CVE-2026-63667","el":"https://www.redsauce.net/el/cves/CVE-2026-63667"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-63667"}}
