Kerentanan Improper Control of Generation of Code ('Code Injection') pada nyariv sandboxjs. Skor CVSS 3.1 10.0 (Critical) menurut github.com.

Deskripsi (NVD)

SandboxJS is a JavaScript sandboxing library. Prior to 0.9.6, sandbox-defined functions expose Function.caller, allowing sandboxed code to recover the internal LispType.Call runtime callback. That callback can then be invoked with attacker-controlled fake context and obj values to extract blocked host statics, recover the real host Function constructor, and execute arbitrary host JavaScript. This vulnerability is fixed in 0.9.6.
