Sandboxed code can read and write to host-realm buffers by acquiring ArrayBuffers from small allocations, leading to sensitive data exposure and potential denial-of-service.\n\n## Affected packages\n\n- `vm2 <= 3.11.6`\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":[]}
