CVE-2026-47135

CVE-2026-47135 vm2 sandbox escape : The vm2 sandbox (Node.js) before 3.11.4 exposes real cross-realm Node.js symbols due to an incomplete Symbol.for override (only blocks two of nine dangerous symbols) and missing isDangerousCrossRealmSymbol checks in bridge write traps (set/defineProperty/delete...

CVE-2026-47135 vm2: Sandbox escape via unblocked cross-realm Symbol.for keys + missing bridge write-trap symbol checks

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, Symbol.for override in setup-sandbox.js only intercepts 2 of 9 dangerous Node.js cross-realm symbols. Combined with the bridge's set/defineProperty/deleteProperty traps having no isDangerousCrossRealmSymbol key check, sandbox...

AgentShield: Deception-Based Compromise Detection for Tool-Using LLM Agents

Defenses against indirect prompt injection IPI in tool-using LLM agents share two structural weaknesses. First, they all attempt to prevent attacks rather than detect the compromises that slip through. Second, they have only been evaluated in English, leaving users of low-resource languages such ...

Arbitrary Code Injection

Overview org.webjars.npm:vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Arbitrary Code Injection through the BaseHandler write traps in lib/bridge.js. An attacker can mutate host Object.prototype,...

Arbitrary Code Injection

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Arbitrary Code Injection through the proxy trap methods in createBridge in the bridge handler code. An attacker can leak a handler using...

EUVD-2026-23937

NEMU OpenXiangShan/NEMU before v2025.12.r2 contains an improper instruction-validation flaw in its RISC-V Vector RVV decoder. The decoder does not correctly validate the funct3 field when decoding vsetvli/vsetivli/vsetvl, allowing certain invalid OP-V instruction encodings to be misinterpreted an...

GHSA-QQFJ-4VCM-26HV Wasmtime segfault or unused out-of-sandbox load with `f64x2.splat` operator on x86-64

On x86-64 platforms with SSE3 disabled Wasmtime's compilation of the f64x2.splat WebAssembly instruction with Cranelift may load 8 more bytes than is necessary. When signals-based-traps are disabled this can result in a uncaught segfault due to loading from unmapped guard pages. With guard pages...

CVE-2026-34971 Wasmtime miscompiled guest heap access enables sandbox escape on aarch64 Cranelift

Wasmtime is a runtime for WebAssembly. From 32.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime's Cranelift compilation backend contains a bug on aarch64 when performing a certain shape of heap accesses which means that the wrong address is accessed. When combined with explicit bounds checks a...

Block the Prompt, Not the Work: The End of "Doctor No"

There is a character that keeps appearing in enterprise security departments, and most CISOs know exactly who that is. It doesn’t build. It doesn’t enable. Its entire function is to say "No." No to ChatGPT. No to DeepSeek. No to the file-sharing tool the product team swears by. For years, this...
