CVE-2026-42038

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, he fix for noproxy hostname normalization bypass is incomplete. When noproxy=localhost is set, requests to 127.0.0.1 and ::1 still route through the proxy instead of bypassing it. The shouldBypassProxy...

CVE-2026-42039

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, toFormData recursively walks nested objects with no depth limit, so a deeply nested value passed as request data crashes the Node.js process with a RangeError. This vulnerability is fixed in 1.15.1 and...

CVE-2026-42035

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, a prototype pollution gadget exists in the Axios HTTP adapter lib/adapters/http.js that allows an attacker to inject arbitrary HTTP headers into outgoing requests. The vulnerability exploits duck-type...

nodejs: Nodejs filesystem permissions bypass

A file access flaw has been discovered in NodeJS. A file's access and modification timestamps to be changed via futimes even when the process has only read permissions. Unlike utimes, futimes does not apply the expected write-permission checks, which means file metadata can be modified in read-on...

nodejs: v8: Node.js: Denial of Service via V8 string hashing mechanism due to predictable hash collisions

A flaw was found in V8's string hashing mechanism within Node.js. A remote attacker can exploit this vulnerability by crafting requests containing integer-like strings. These specially crafted strings cause predictable hash collisions in V8's internal string table, particularly when processed by...

Node.js: Node.js: Denial of Service due to crafted HTTP `__proto__` header

A flaw was found in Node.js. A remote attacker can exploit this vulnerability by sending a specially crafted HTTP request that includes a header named proto. When a Node.js application processes this request and attempts to access distinct headers, it encounters an unhandled error, leading to an...

CVE-2026-34211

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.36, the @nyariv/sandboxjs parser contains unbounded recursion in the restOfExp function and the lispify/lispifyExpr call chain. An attacker can crash any Node.js process that parses untrusted input by supplying deeply nested expressions...

BIT-NODE-MIN-2026-21714

A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOWUPDATE frames on stream 0 connection-level that cause the flow control window to exceed the maximum value of 2³¹-1. The server correctly sends a GOAWAY frame, but the Http2Session object is never cleaned up. This vulnerabili...

A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOWUPDATE frames on stream 0 connection-level that cause the flow control window to exceed the maximum value of 2³¹-1. The server correctly sends a GOAWAY frame, but the Http2Session object is never cleaned up. This vulnerabili...

CVE-2026-21717

A flaw in V8's string hashing mechanism causes integer-like strings to be hashed to their numeric value, making hash collisions trivially predictable. By crafting a request that causes many such collisions in V8's internal string table, an attacker can significantly degrade performance of the...

CVE-2026-26830

pdf-image npm package through version 2.0.0 allows OS command injection via the pdfFilePath parameter. The constructGetInfoCommand and constructConvertCommandForPage functions use util.format to interpolate user-controlled file paths into shell command strings that are executed via childprocess.e...

CVE-2026-33285 LiquidJS: memoryLimit Bypass through Negative Range Values Leads to Process Crash

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.1, LiquidJS's memoryLimit security mechanism can be completely bypassed by using reverse range expressions e.g., 100000000..1, allowing an attacker to allocate unlimited memory. Combined wit...
