The package grpc before 1.24.4; the package @grpc/grpc-js before 1.1.8 are vulnerable to Prototype Pollution via loadPackageDefinition.

A State Pollution vulnerability was discovered in the TON Virtual Machine (TVM) before v2025.04. The issue exists in the RUNVM instruction logic (VmState::run_child_vm), which is responsible for initializing child virtual machines. The operation moves critical resources (specifically libraries and log) from the parent state to a new child state in a non-atomic manner. If an Out-of-Gas (OOG) exception occurs after resources are moved but before the state transition is finalized, the parent VM retains a corrupted state where these resources are emptied/invalid. Because RUNVM supports gas isolation, the parent VM continues execution with this corrupted state, leading to unexpected behavior or denial of service within the contract's context.

A flaw was found in the libxslt library. The same memory field, psvi, is used for both stylesheet and input data, which can lead to type confusion during XML transformations. This vulnerability allows an attacker to crash the application or corrupt memory. In some cases, it may lead to denial of service or unexpected behavior.

web3-core-method is a package designed to creates the methods on the web3 modules. A Prototype Pollution vulnerability in the attachToObject function of web3-core-method version 1.10.4 and before allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.

A Prototype Pollution vulnerability in the toCsv function of csvjson versions thru 5.1.0 allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.

The messageformat package, an implementation of the Unicode MessageFormat 2 specification for JavaScript, is vulnerable to prototype pollution due to improper handling of message key paths in versions prior to 2.3.0. The flaw arises when processing nested message keys containing special characters (e.g., __proto__ ), which can lead to unintended modification of the JavaScript Object prototype. This vulnerability may allow a remote attacker to inject properties into the global object prototype via specially crafted message input, potentially causing denial of service or other undefined behaviors in applications using the affected component.

A Prototype Pollution vulnerability in the byGroupAndType function of sassdoc-extras v2.5.1 and before allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.

mpregular is a package that provides a small program development framework based on RegularJS. A Prototype Pollution vulnerability in the mp.addEventHandler function of mpregular version 0.2.0 and before allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.

rollbar is a package designed to effortlessly track and debug errors in JavaScript applications. This package includes advanced error tracking features and an intuitive interface to help you identify and fix issues more quickly. A Prototype Pollution vulnerability in the utility.set function of rollbar v2.26.4 and before allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.

spmrc is a package that provides the rc manager for spm. A Prototype Pollution vulnerability in the set and config function of spmrc version 1.2.0 and before allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.

toggle-array is a package designed to enables a property on the object at the specified index, while disabling the property on all other objects. A Prototype Pollution vulnerability in the enable and disable function of toggle-array v1.0.1 and before allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.

The web3-core-subscriptions is a package designed to manages web3 subscriptions. A Prototype Pollution vulnerability in the attachToObject function of web3-core-subscriptions version 1.10.4 and before allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.

All versions of package bignum are vulnerable to Denial of Service (DoS) due to a type-check exception in V8, when verifying the type of the second argument to the .powm function, V8 will crash regardless of Node try/catch blocks.

This affects all versions of package mout. The deepFillIn function can be used to 'fill missing properties recursively', while the deepMixIn mixes objects into the target object, recursively mixing existing child objects as well. In both cases, the key used to access the target object recursively is not checked, leading to exploiting this vulnerability. **Note:** This vulnerability derives from an incomplete fix of [CVE-2020-7792](https://security.snyk.io/vuln/SNYK-JS-MOUT-1014544).

An unauthenticated remote attacker may cause the visualisation server of the CODESYS Control runtime system to access a resource with a pointer of wrong type, potentially leading to a denial-of-service (DoS) condition.

A type confusion issue was addressed with improved checks. This issue is fixed in macOS Monterey 12.7.6, macOS Sonoma 14.6, macOS Ventura 13.6.8. An attacker may be able to cause unexpected app termination.

Versions of the package web3-utils before 4.2.1 are vulnerable to Prototype Pollution via the utility functions format and mergeDeep, due to insecure recursive merge. An attacker can manipulate an object's prototype, potentially leading to the alteration of the behavior of all objects inheriting from the affected prototype by passing specially crafted input to these functions.

A prototype pollution in the lib.set function of dref v0.1.2 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.
