SandboxJS 代码注入漏洞

SandboxJS is a security assessment tool developed by nyariv. Versions of SandboxJS prior to 0.8.27 contained a code injection vulnerability. This vulnerability stemmed from improper restrictions on lookupGetter, which could lead to sandbox escape or remote code execution...

SandboxJS security vulnerability

SandboxJS is a security assessment tool developed by nyariv. Versions of SandboxJS prior to 0.8.26 contained security vulnerabilities. These vulnerabilities stemmed from the lack of isolation of AsyncFunctions within SandboxFunctions, which could lead to sandbox escapes and remote code execution...

CVE-2026-23830

SandboxJS is a JavaScript sandboxing library. Versions prior to 0.8.26 have a sandbox escape vulnerability due to AsyncFunction not being isolated in SandboxFunction. The library attempts to sandbox code execution by replacing the global Function constructor with a safe, sandboxed version...

CVE-2026-23830

SandboxJS (pre-0.8.26) contains a sandbox escape where AsyncFunction (and related constructors) are not isolated in SandboxFunction. The safe-replacement map omits AsyncFunction, GeneratorFunction, and AsyncGeneratorFunction, so accessing an async function’s .constructor can yield the native host...

SandboxJS has Sandbox Escape via Unprotected AsyncFunction Constructor

Summary A sandbox escape vulnerability due to AsyncFunction not being isolated in SandboxFunction Details The library attempts to sandbox code execution by replacing the global Function constructor with a safe, sandboxed version SandboxFunction. This is handled in utils.ts by mapping Function to...

Improper Control of Dynamically-Managed Code Resources

Overview @nyariv/sandboxjs is a Javascript sandboxing library.
