| CVE-2021-32619 | Cri | 0.64 | 9.8 | 0.01 | May 28, 2021 | Deno is a runtime for JavaScript and TypeScript that uses V8 and is built in Rust. In Deno versions 1.5.0 to 1.10.1, modules that are dynamically imported through `import()` or `new Worker` might have been able to bypass network and file system permission checks when statically… | ||
| CVE-2022-24783 | Cri | 0.58 | 10.0 | 0.01 | Mar 25, 2022 | Deno is a runtime for JavaScript and TypeScript. The versions of Deno between release 1.18.0 and 1.20.2 (inclusive) are vulnerable to an attack where a malicious actor controlling the code executed in a Deno runtime could bypass all permission checks and execute arbitrary shell… | ||
| CVE-2023-28445 | Cri | 0.57 | 9.9 | 0.01 | Mar 24, 2023 | Deno is a runtime for JavaScript and TypeScript that uses V8 and is built in Rust. Resizable ArrayBuffers passed to asynchronous functions that are shrunk during the asynchronous operation could result in an out-of-bound read/write. It is unlikely that this has been exploited in… | ||
| CVE-2024-34346 | Hig | 0.55 | 8.4 | 0.00 | May 7, 2024 | Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults. The Deno sandbox may be unexpectedly weakened by allowing file read/write access to privileged files in various locations on Unix and Windows platforms. For example, reading `/proc/self/environ` may… | ||
| CVE-2024-27934 | Hig | 0.55 | 8.4 | 0.00 | Mar 21, 2024 | Deno is a JavaScript, TypeScript, and WebAssembly runtime. Starting in version 1.36.2 and prior to version 1.40.3, use of inherently unsafe `*const c_void` and `ExternalPointer` leads to use-after-free access of the underlying structure, resulting in arbitrary code execution.… | ||
| CVE-2025-48935 | Cri | 0.52 | 9.1 | 0.00 | Jun 4, 2025 | Deno is a JavaScript, TypeScript, and WebAssembly runtime. Starting in version 2.2.0 and prior to versions 2.2.5, it is possible to bypass Deno's permission read/write db permission check by using `ATTACH DATABASE` statement. Version 2.2.5 contains a patch for the issue. | ||
| CVE-2024-32477 | Hig | 0.50 | 7.7 | 0.00 | Apr 18, 2024 | Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults. By using ANSI escape sequences and a race between `libc::tcflush(0, libc::TCIFLUSH)` and reading standard input, it's possible to manipulate the permission prompt and force it to allow an unsafe… | ||

Starting in version 1.32.1 and prior to version 1.41.0 of the deno library, maliciously crafted permission request can show the spoofed permission prompt by inserting a broken ANSI escape sequence… | ||
| CVE-2023-28446 | Hig | 0.50 | 8.8 | 0.01 | Mar 24, 2023 | Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust. Arbitrary program names without any ANSI filtering allows any malicious program to clear the first 2 lines of a `op_spawn_child` or `op_kill` prompt and replace it with… | ||
| CVE-2023-33966 | Hig | 0.49 | 8.6 | 0.01 | May 31, 2023 | Deno is a runtime for JavaScript and TypeScript. In deno 1.34.0 and deno_runtime 0.114.0, outbound HTTP requests made using the built-in `node:http` or `node:https` modules are incorrectly not checked against the network permission allow list (`--allow-net`). Dependencies… | ||
| CVE-2021-41641 | Hig | 0.48 | 8.4 | 0.00 | Jun 12, 2022 | Deno <=1.14.0 file sandbox does not handle symbolic links correctly. When running Deno with specific write access, the Deno.symlink method can be used to gain access to any directory. | ||
| CVE-2026-49402 | Hig | 0.46 | 8.1 | 0.00 | Jun 23, 2026 | Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.7.10, Deno's node:child_process implementation provided an escapeShellArg() helper used when callers passed shell: true to spawn / spawnSync / exec and friends. On Windows, the helper failed to quote arguments… | ||
| CVE-2026-32260 | Hig | 0.46 | 8.1 | 0.01 | Mar 12, 2026 | Deno is a JavaScript, TypeScript, and WebAssembly runtime. From 2.7.0 to 2.7.1, A command injection vulnerability exists in Deno's node:child_process polyfill (shell: true mode) that bypasses the fix for CVE-2026-27190. The two-stage argument sanitization in… | ||
| CVE-2026-27190 | Hig | 0.46 | 8.1 | 0.02 | Feb 20, 2026 | Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.6.8, a command injection vulnerability exists in Deno's node:child_process implementation. This vulnerability is fixed in 2.6.8. | ||
| CVE-2026-22864 | Hig | 0.46 | 8.1 | 0.01 | Jan 15, 2026 | Deno is a JavaScript, TypeScript, and WebAssembly runtime. Before 2.5.6, a prior patch aimed to block spawning Windows batch/shell files by returning an error when a spawned path’s extension matched .bat or .cmd. That check performs a case-sensitive comparison against… | ||
| CVE-2025-61787 | Hig | 0.46 | 8.1 | 0.02 | Oct 8, 2025 | Deno is a JavaScript, TypeScript, and WebAssembly runtime. Versions prior to 2.5.3 and 2.2.15 are vulnerable to Command Line Injection attacks on Windows when batch files are executed. In Windows, ``CreateProcess()`` always implicitly spawns ``cmd.exe`` if a batch file (.bat,… | ||
| CVE-2024-27933 | Hig | 0.46 | 8.2 | 0.02 | Mar 21, 2024 | Deno is a JavaScript, TypeScript, and WebAssembly runtime. In version 1.39.0, use of raw file descriptors in `op_node_ipc_pipe()` leads to premature close of arbitrary file descriptors, allowing standard input to be re-opened as a different resource resulting in permission… | ||
| CVE-2026-22863 | Hig | 0.42 | 7.5 | 0.00 | Jan 15, 2026 | Deno is a JavaScript, TypeScript, and WebAssembly runtime. Before 2.6.0, node:crypto doesn't finalize cipher. The vulnerability allows an attacker to have infinite encryptions. This can lead to naive attempts at brute forcing, as well as more refined attacks with the goal to… | ||
| CVE-2025-21620 | Hig | 0.42 | 7.5 | 0.01 | Jan 6, 2025 | Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults. When you send a request with the Authorization header to one domain, and the response asks to redirect to a different domain, Deno'sfetch() redirect handling creates a follow-up redirect request that… | ||
| CVE-2023-22499 | Hig | 0.42 | 7.5 | 0.01 | Jan 17, 2023 | Deno is a runtime for JavaScript and TypeScript that uses V8 and is built in Rust. Multi-threaded programs were able to spoof interactive permission prompt by rewriting the prompt to suggest that program is waiting on user confirmation to unrelated action. A malicious program… |
