Node.js Module axios < 0.33.0 / 1.x < 1.18.0 Prototype Pollution

The version of the axios Node.js module installed on the remote host is prior to 0.33.0 or 1.x prior to 1.18.0. It is, therefore, affected by multiple vulnerabilities: - axios is vulnerable to read-side prototype-pollution gadgets that can alter request construction when Object.prototype has...

CVE-2026-67319

axios before 0.33.0 and 1.x before 1.18.0 can consume inherited properties from nested request option objects when the JavaScript process's Object.prototype has already been polluted by another component. While the top-level merged config uses a null prototype, nested plain objects such as auth a...

CVE-2026-59952

Valibot has a concrete vulnerability CVE-2026-59952 in versions prior to 1.4.2 where record() can produce issue paths containing attacker-controlled Object.prototype-like keys (e.g., toString, valueOf, hasOwnProperty). When flatten() processes these issues, flatErrors.nested[dotPath] resolves to ...

CVE-2026-59952 Valibot: record() issue paths can make flatten() throw for inherited Object property names

Valibot helps validate data using a schema. Versions prior to 1.4.2 can throw a TypeError inside its flatten helper when validation issues contain attacker-controlled object keys such as toString, valueOf, or hasOwnProperty. The issue is reachable through normal record validation. record...

CVE-2026-44290

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.6 and 8.0.2, protobufjs allowed certain schema option paths to traverse through inherited object properties while applying options. A crafted protobuf schema or JSON descriptor could cause option handling to write...

CVE-2026-44290 protobufjs: Process-wide denial of service through unsafe option paths

Svelte 安全漏洞

Svelte is an open-source approach to building web applications developed by Svelte. Versions of Svelte prior to 5.51.5 have a security vulnerability. This vulnerability arises from server-side rendering, where property extensions enumerate inherited properties, which may lead to unexpected proper...

Svelte SSR attribute spreading includes inherited properties from prototype chain

In server-side rendering, attribute spreading on elements e.g. enumerates inherited properties from the object's prototype chain rather than only own properties. In environments where Object.prototype has already been polluted — a precondition outside of Svelte's control — this can cause unexpect...
