{"apiVersion":"1.0","identifier":"CVE-2026-47683","description":"vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.6, the bufferAllocLimit enforcement in lib/setup-sandbox.js does not cover Buffer.concat(list, totalLength) or Buffer.from(arrayLike) with an attacker-controlled length, allowing sandbox code to perform large synchronous host external-memory allocations that bypass the configured cap and can exhaust the host process. This issue is fixed in version 3.11.6.","publishedAt":"2026-08-17T21:16:45","lastModifiedAt":"2026-08-18T16:17:10","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-47683","cvssScore":8.7,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.0031,"riskScore":0.89,"affectedProduct":"vm2","affectedVersions":"<3.11.6","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-47683","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-47683","en":"https://www.redsauce.net/en/cves/CVE-2026-47683","fr":"https://www.redsauce.net/fr/cves/CVE-2026-47683","pt":"https://www.redsauce.net/pt/cves/CVE-2026-47683","de":"https://www.redsauce.net/de/cves/CVE-2026-47683","sk":"https://www.redsauce.net/sk/cves/CVE-2026-47683","el":"https://www.redsauce.net/el/cves/CVE-2026-47683"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-47683"}}
