CVSS v3.1 |
| Impact:
Lodash versions 4.17.23 and earlier are vulnerable to prototype pollution in the _.unset and _.omit functions. The fix for (CVE-2025-13465: https://github.com/lodash/lodash/security/advisories/GHSA-xxjr-mmjv-4gpg) only guards against string key members, so an attacker can bypass the check by passing array-wrapped path segments. This allows deletion of properties from built-in prototypes such as Object.prototype, Number.prototype, and String.prototype.
The issue permits deletion of prototype properties but does not allow overwriting their original behavior.
Patches:
This issue is patched in 4.18.0.
Workarounds:
None. Upgrade to the patched version. |
| 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. |
| In versions before 20.0.2, it was found that --disallow-code-generation-from-strings is not sufficient for isolating untrusted JavaScript in happy-dom. The untrusted script and the rest of the application still run in the same Isolate/process, so attackers can deploy prototype pollution payloads to hijack important references like "process" in the example below, or to hijack control flow via flipping checks of undefined property. This vulnerability is due to an incomplete fix for CVE-2025-61927. The vulnerability is fixed in 20.0.2. |
| A prototype pollution in the lib function of php-date-formatter v1.3.6 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload. |
| The latest version of utils-extend (1.0.8) is vulnerable to Prototype Pollution through the entry function(s) lib.extend. An attacker can supply a payload with Object.prototype setter to introduce or modify properties within the global prototype chain, causing denial of service (DoS) a the minimum consequence. |
| A vulnerability exists in the 'min-document' package prior to version 2.19.0, stemming from improper handling of namespace operations in the removeAttributeNS method. By processing malicious input involving the __proto__ property, an attacker can manipulate the prototype chain of JavaScript objects, leading to denial of service or arbitrary code execution. This issue arises from insufficient validation of attribute namespace removal operations, allowing unintended modification of critical object prototypes. The vulnerability remains unaddressed in the latest available version. |
| aofl cli-lib v3.14.0 was discovered to contain a prototype pollution via the component defaultsDeep. This vulnerability allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties. |
| @std/toml is the Deno Standard Library. Prior to version 1.0.9, an attacker can pollute the prototype chain in Node.js runtime and Browser when parsing untrusted TOML data, thus achieving Prototype Pollution (PP) vulnerability. This is because the library is merging an untrusted object with an empty object, which by default the empty object has the prototype chain. This issue has been patched in version 1.0.9. |
| content-security-policy-parser parses content security policy directives. A prototype pollution vulnerability exists in versions 0.5.0 and earlier, wherein if a policy name is called __proto__, one can override the Object prototype. This issue has been patched in version 0.6.0. A workaround involves disabling prototype method in NodeJS, neutralizing all possible prototype pollution attacks. Provide either --disable-proto=delete (recommended) or --disable-proto=throw as an argument to node to enable this feature. |
| pdfme is a TypeScript-based PDF generator and React-based UI. The expression evaluation feature in pdfme 5.2.0 to 5.4.0 contains critical vulnerabilities allowing sandbox escape leading to XSS and prototype pollution attacks. This vulnerability is fixed in 5.4.1. |
| A prototype pollution in the lib.combine function of php-parser v3.2.1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload. |
| harvey-woo cat5th/key-serializer v0.2.5 was discovered to contain a prototype pollution via the function "query". This vulnerability allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties. |
| che3vinci c3/utils-1 1.0.131 was discovered to contain a prototype pollution via the function assign. This vulnerability allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties. |
| ahilfoley cahil/utils v2.3.2 was discovered to contain a prototype pollution via the function set. This vulnerability allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties. |
| 2o3t-utility v0.1.2 was discovered to contain a prototype pollution via the function extend. This vulnerability allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties. |
| njwt up to v0.4.0 was discovered to contain a prototype pollution in the Parser.prototype.parse method. |
| All versions of the package node-gettext are vulnerable to Prototype Pollution via the addTranslations() function in gettext.js due to improper user input sanitization. |
| Versions of the package mysql2 before 3.9.8 are vulnerable to Prototype Pollution due to improper user input sanitization passed to fields and tables when using nestTables. |
| sveltekit-superforms makes SvelteKit forms a pleasure to use. sveltekit-superforms v2.27.3 and prior are susceptible to a prototype pollution vulnerability within the parseFormData function of formData.js. An attacker can inject string and array properties into Object.prototype, leading to denial of service, type confusion, and potential remote code execution in downstream applications that rely on polluted objects. This vulnerability is fixed in 2.27.4. |
| A prototype pollution in the lib.parse function of dot-qs v0.2.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload. |
