CVSS v3.1 |
| flatted is a circular JSON parser. Prior to version 3.4.2, the parse() function in flatted can use attacker-controlled string values from the parsed JSON as direct array index keys, without validating that they are numeric. Since the internal input buffer is a JavaScript Array, accessing it with the key "__proto__" returns Array.prototype via the inherited getter. This object is then treated as a legitimate parsed value and assigned as a property of the output object, effectively leaking a live reference to Array.prototype to the consumer. Any code that subsequently writes to that property will pollute the global prototype. This issue has been patched in version 3.4.2. |
| Qwik is a performance-focused JavaScript framework. Versions prior to 1.19.2 improperly inferred arrays from dotted form field names during FormData parsing. By submitting mixed array-index and object-property keys for the same path, an attacker could cause user-controlled properties to be written onto values that application code expected to be arrays. When processing application/x-www-form-urlencoded or multipart/form-data requests, Qwik City converted dotted field names (e.g., items.0, items.1) into nested structures. If a path was interpreted as an array, additional attacker-supplied keys on that path—such as items.toString, items.push, items.valueOf, or items.length—could alter the resulting server-side value in unexpected ways, potentially leading to request handling failures, denial of service through malformed array state or oversized lengths, and type confusion in downstream code. This issue was fixed in version 1.19.2. |
| Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't sufficient for the job. In devalue v5.6.3 and earlier, devalue.parse and devalue.unflatten were susceptible to prototype pollution via maliciously crafted payloads. Successful exploitation could lead to Denial of Service (DoS) or type confusion. This vulnerability is fixed in 5.6.4. |
| In AngularJS before 1.7.9 the function `merge()` could be tricked into adding or modifying properties of `Object.prototype` using a `__proto__` payload. |
| Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') in jquery-bbq 1.2.1 allows a malicious user to inject properties into Object.prototype. |
| js-toml is a TOML parser for JavaScript, fully compliant with the TOML 1.0.0 Spec. In versions below 1.0.2, a prototype pollution vulnerability in js-toml allows a remote attacker to add or modify properties of the global Object.prototype by parsing a maliciously crafted TOML input. This is fixed in version 1.0.2. |
| Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') in jquery-deparam 0.5.1 allows a malicious user to inject properties into Object.prototype. |
| hoek before 8.5.1 and 9.x before 9.0.3 allows prototype poisoning in the clone function. |
| Prototype pollution vulnerability in '101' versions 1.0.0 through 1.6.3 allows an attacker to cause a denial of service and may lead to remote code execution. |
| Prototype pollution vulnerability in 'deep-override' versions 1.0.0 through 1.0.1 allows an attacker to cause a denial of service and may lead to remote code execution. |
| Prototype pollution vulnerability in 'safe-obj' versions 1.0.0 through 1.0.2 allows an attacker to cause a denial of service and may lead to remote code execution. |
| Prototype pollution vulnerability in 'safe-flat' versions 2.0.0 through 2.0.1 allows an attacker to cause a denial of service and may lead to remote code execution. |
| Prototype pollution vulnerability in 'patchmerge' versions 1.0.0 through 1.0.1 allows an attacker to cause a denial of service and may lead to remote code execution. |
| Prototype pollution vulnerability in 'changeset' versions 0.0.1 through 0.2.5 allows an attacker to cause a denial of service and may lead to remote code execution. |
| Prototype pollution vulnerability in 'object-collider' versions 1.0.0 through 1.0.3 allows attacker to cause a denial of service and may lead to remote code execution. |
| A vulnerability classified as critical has been found in Furqan node-whois. Affected is an unknown function of the file index.coffee. The manipulation leads to improperly controlled modification of object prototype attributes ('prototype pollution'). It is possible to launch the attack remotely. The name of the patch is 46ccc2aee8d063c7b6b4dee2c2834113b7286076. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-216252. |
| This affects the package json-pointer before 0.6.1. Multiple reference of object using slash is supported. |
| Prototype pollution vulnerability in function DEFNODE in ast.js in mishoo UglifyJS 3.13.2 via the name variable in ast.js. NOTE: the vendor considers this an invalid report. |
| All versions of package querymen are vulnerable to Prototype Pollution if the parameters of exported function handler(type, name, fn) can be controlled by users without any sanitization. Note: This vulnerability derives from an incomplete fix of [CVE-2020-7600](https://security.snyk.io/vuln/SNYK-JS-QUERYMEN-559867). |
| 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). |
