This link is maintained to preserve external references.\n\n## Original Description\nvm2 versions from 3.11.0 before 3.11.8 fail to protect host TypedArray and ArrayBuffer prototypes from sandbox mutation. Attackers can use prototype-walking primitives to reach and modify host Uint8Array.prototype, %TypedArray%.prototype, and ArrayBuffer.prototype, causing host-created typed arrays to observe attacker-controlled properties after VM.run() returns.\n\n## Affected packages\n\n- `vm2 >= 3.11.0, <= 3.11.7`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"midnight","depthScore":55,"depthScoreParts":{"impact":55,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
