CVE-2026-49406— Deno Land Deno 路径遍历漏洞

Deno: BYONM module resolution allows `package.json` main path traversal to bypass `--allow-read` restrictions

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.7.12, when Deno was run in BYONM mode (nodeModulesDir: "manual"), the module resolver did not validate that a package's resolved entrypoint stayed within its node_modules/<pkg>/ directory. A malicious package.json whose main field contained .. segments was able to resolve to an arbitrary path on disk, and the resolver then read that file without consulting the --allow-read allowlist. This let a require("evil-pkg") call return the contents of a file that a direct Deno.readTextFileSync(...) call would have been blocked from reading. This vulnerability is fixed in 2.7.12.

对路径名的限制不恰当(路径遍历)

Deno Land Deno 路径遍历漏洞

Deno是Deno组织开源的一个简单、现代且安全的 JavaScript 和 TypeScript 运行环境。 Deno Land Deno 2.7.12之前版本存在路径遍历漏洞，该漏洞源于模块解析器在BYONM模式下未验证包的入口点是否在node_modules/<pkg>/目录内，导致恶意package.json中的..段可解析到磁盘上的任意路径，并绕过--allow-read白名单读取文件。
