CVE-2026-92953: vm2 3.11.0 through 3.11.7 Prototype Pollution via TypedArray
vm2 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.

Improper Control of Dynamically-Managed Code Resources
Improper Control of Dynamically-Managed Code Resources represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
