CVE-2026-42264

Axios is a promise based HTTP client for the browser and Node.js. From version 1.0.0 to before version 1.15.2, fFive config properties auth, baseURL, socketPath, beforeRedirect, and insecureHTTPParser in the HTTP adapter are read via direct property access without hasOwnProperty guards, making th...

Prototype Pollution

Axios is vulnerable to Prototype Pollution. The vulnerability is due to missing hasOwnProperty checks when reading object properties, which allows an attacker to exploit polluted prototypes to intercept and modify JSON responses or hijack HTTP transport, gaining access to sensitive request data...

CVE-2026-42033

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, when Object.prototype has been polluted by any co-dependency with keys that axios reads without a hasOwnProperty guard, an attacker can a silently intercept and modify every JSON response before the...

Arbitrary Code Execution

SandboxJS is vulnerable to a sandbox escape vulnerability. The vulnerability is due to inconsistent key validation during property access, where the key is sanitized using hasOwnPropertykey but not strictly enforced as a string, allowing attackers to supply crafted objects that coerce to differen...

CVE-2026-25586

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.29, a sandbox escape is possible by shadowing hasOwnProperty on a sandbox object, which disables prototype whitelist enforcement in the property-access path. This permits direct access to proto and other blocked prototype properties,...

CVE-2026-25641

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.29, there is a sandbox escape vulnerability due to a mismatch between the key on which the validation is performed and the key used for accessing properties. Even though the key used in property accesses is annotated as string, this is...

SandboxJS 安全漏洞

SandboxJS is a security assessment tool developed by nyariv’s individual developer. Versions of SandboxJS prior to 0.8.29 contained a security vulnerability. This vulnerability stemmed from the use of hasOwnProperty to mask objects in the sandbox, allowing sandbox escape and disabling the prototy...

GHSA-JJPW-65FV-8G48 @nyariv/sandboxjs has Sandbox Escape via Prototype Whitelist Bypass and Host Prototype Pollution

Summary A sandbox escape is possible by shadowing hasOwnProperty on a sandbox object, which disables prototype whitelist enforcement in the property-access path. This permits direct access to proto and other blocked prototype properties, enabling host Object.prototype pollution and persistent...

Prototype Pollution

Overview @nyariv/sandboxjs is a Javascript sandboxing library. Affected versions of this package are vulnerable to Prototype Pollution via prototypeAccess on a shadowed sandbox object's hasOwnProperty. An attacker can execute arbitrary code on the underlying system by bypassing the prototype...

PT-2026-6652

SandboxJS and Affected Versions SandboxJS versions prior to 0.8.29 Description SandboxJS, a JavaScript sandboxing library, is susceptible to a sandbox escape issue. This occurs because of the ability to shadow the hasOwnProperty method on a sandbox object, which disables prototype whitelist...

GHSA-2CP6-34R9-54XX Maker.js has Unsafe Property Copying in makerjs.extendObject

Summary The makerjs.extendObject function copies properties from source objects without proper validation, potentially exposing applications to security risks. The function lacks hasOwnProperty checks and does not filter dangerous keys, allowing inherited properties and potentially malicious...
