CVE-2025-62410 1 Capricorn86 1 Happy-dom 2026-04-15 10.0 Critical
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.
CVE-2024-57063 2026-04-15 7.5 High
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.
CVE-2025-55164 1 Content-security-policy-parser Project 1 Content-security-policy-parser 2026-04-15 N/A
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.
CVE-2024-57067 2026-04-15 7.5 High
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.
CVE-2024-57072 2026-04-15 7.5 High
A prototype pollution in the lib.requireFromString function of module-from-string v3.3.1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.
CVE-2025-57820 1 Svelte 1 Devalue 2026-04-15 N/A
Svelte devalue is a utility library. Prior to version 5.3.2, a string passed to devalue.parse could represent an object with a __proto__ property and devalue.parse does not check that an index is numeric. This could result in assigning prototypes to objects and properties, leading to prototype pollution. This issue has been fixed in version 5.3.2
CVE-2024-21505 2026-04-15 7.5 High
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.
CVE-2024-57086 2026-04-15 7.5 High
A prototype pollution in the function fieldsToJson of node-opcua-alarm-condition v2.134.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.
CVE-2024-39013 1 2o3t 1 2o3t-utility 2026-04-15 9.8 Critical
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.
CVE-2024-36582 1 Alykoshin 1 Mini-deep-assign 2026-04-15 9.8 Critical
alexbinary object-deep-assign 1.0.11 is vulnerable to Prototype Pollution via the extend() method of Module.deepAssign (/src/index.js)
CVE-2025-8083 1 Vuetifyjs 1 Vuetify 2026-04-15 8.6 High
The Preset configuration https://v2.vuetifyjs.com/en/features/presets  feature of Vuetify is vulnerable to Prototype Pollution https://cheatsheetseries.owasp.org/cheatsheets/Prototype_Pollution_Prevention_Cheat_Sheet.html  due to the internal 'mergeDeep' utility function used to merge options with defaults. Using a specially-crafted, malicious preset can result in polluting all JavaScript objects with arbitrary properties, which can further negatively affect all aspects of the application's behavior. This can lead to a wide range of security issues, including resource exhaustion/denial of service or unauthorized access to data. If the application utilizes Server-Side Rendering (SSR), this vulnerability could affect the whole server process. This issue affects Vuetify versions greater than or equal to 2.2.0-beta.2 and less than 3.0.0-alpha.10. Note: Version 2.x of Vuetify is End-of-Life and will not receive any updates to address this issue. For more information see here https://v2.vuetifyjs.com/en/about/eol/ .
CVE-2024-57064 2026-04-15 7.5 High
A prototype pollution in the lib.setValue function of @syncfusion/ej2-spreadsheet v27.2.2 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload. NOTE: the Supplier disputes this because they found that the lib.setValue function is not utilized.
CVE-2025-62517 1 Rollbar 1 Rollbar 2026-04-15 5.9 Medium
Rollbar.js offers error tracking and logging from Javascript to Rollbar. In versions before 2.26.5 and from 3.0.0-alpha1 to before 3.0.0-beta5, there is a prototype pollution vulnerability in merge(). If application code calls rollbar.configure() with untrusted input, prototype pollution is possible. This issue has been fixed in versions 2.26.5 and 3.0.0-beta5. A workaround involves ensuring that values passed to rollbar.configure() do not contain untrusted input.
CVE-2024-38999 1 Jrburke 1 Requirejs 2026-04-15 10 Critical
jrburke requirejs v2.3.6 was discovered to contain a prototype pollution via the function s.contexts._.configure. This vulnerability allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties.
CVE-2025-57351 2026-04-15 6.5 Medium
A prototype pollution vulnerability exists in the ts-fns package versions prior to 13.0.7, where insufficient validation of user-provided keys in the assign function allows attackers to manipulate the Object.prototype chain. By leveraging this flaw, adversaries may inject arbitrary properties into the global object's prototype, potentially leading to application crashes, unexpected code execution behaviors, or bypasses of security-critical validation logic dependent on prototype integrity. The vulnerability stems from improper handling of deep property assignment operations within the library's public API functions. This issue remains unaddressed in the latest available version.
CVE-2025-26278 2026-04-15 7.5 High
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.
CVE-2024-24293 1 Miguelcastillo 1 Bit-loader 2026-04-15 8.8 High
A Prototype Pollution issue in MiguelCastillo @bit/loader v.10.0.3 allows an attacker to execute arbitrary code via the M function e argument in index.js.
CVE-2025-13158 1 Apidocjs 1 Apidoc-core 2026-04-15 N/A
Prototype pollution vulnerability in apidoc-core versions 0.2.0 and all subsequent versions allows remote attackers to modify JavaScript object prototypes via malformed data structures, including the “define” property processed by the application, potentially leading to denial of service or unintended behavior in applications relying on the integrity of prototype chains. This affects the preProcess() function in api_group.js, api_param_title.js, api_use.js, and api_permission.js worker modules.
CVE-2024-57080 2026-04-15 7.5 High
A prototype pollution in the lib.install function of vxe-table v4.8.10 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.
CVE-2025-3197 2026-04-15 7.3 High
Versions of the package expand-object from 0.0.0 are vulnerable to Prototype Pollution in the expand() function in index.js. This function expands the given string into an object and allows a nested property to be set without checking the provided keys for sensitive properties like __proto__.
