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-2025-55195 1 Denoland 1 Std 2026-04-15 7.3 High
@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.
CVE-2025-8101 1 Linkify 1 Linkify 2026-04-15 8.6 High
Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') vulnerability in Linkify (linkifyjs) allows XSS Targeting HTML Attributes and Manipulating User-Controlled Variables.This issue affects Linkify: from 4.3.1 before 4.3.2.
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-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-2024-21512 2026-04-15 8.2 High

CVE-2024-21528 1 Redhat 1 Openshift Data Foundation 2026-04-15 5.9 Medium
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.
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-2024-21548 2026-04-15 7.5 High
Versions of the package bun after 0.0.12 and before 1.1.30 are vulnerable to Prototype Pollution due to improper input sanitization. An attacker can exploit this vulnerability through Bun's APIs that accept objects. **Note:** This issue relates to the widely known and actively developed 'Bun' JavaScript runtime. The bun package on NPM at versions 0.0.12 and below belongs to a different and older project that happened to claim the 'bun' name in the past.
CVE-2024-29650 2026-04-15 9.8 Critical
An issue in @thi.ng/paths v.5.1.62 and before allows a remote attacker to execute arbitrary code via the mutIn and mutInManyUnsafe components.
CVE-2024-29651 1 Apidevtools 1 Json-schema-ref-parser 2026-04-15 8.1 High
A Prototype Pollution issue in API Dev Tools json-schema-ref-parser v.11.0.0 and v.11.1.0 allows a remote attacker to execute arbitrary code via the bundle()`, `parse()`, `resolve()`, `dereference() functions.
CVE-2024-32866 1 Edmundhung 1 Conform 2026-04-15 8.6 High
Conform, a type-safe form validation library, allows the parsing of nested objects in the form of `object.property`. Due to an improper implementation of this feature in versions prior to 1.1.1, an attacker can exploit the feature to trigger prototype pollution by passing a crafted input to `parseWith...` functions. Applications that use conform for server-side validation of form data or URL parameters are affected by this vulnerability. Version 1.1.1 contains a patch for the issue.
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-2024-36573 1 Almela 1 Obx 2026-04-15 9.8 Critical
almela obx before v.0.0.4 has a Prototype Pollution issue which allows arbitrary code execution via the obx/build/index.js:656), reduce (@almela/obx/build/index.js:470), Object.set (obx/build/index.js:269) component.
CVE-2024-36574 1 Amirziai 1 Flatten Json 2026-04-15 6.3 Medium
A Prototype Pollution issue in flatten-json 1.0.1 allows an attacker to execute arbitrary code via module.exports.unflattenJSON (flatten-json/index.js:42)
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-2025-57352 2026-04-15 5.3 Medium
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.
CVE-2025-70956 1 Ton-blockchain 1 Ton 2026-04-15 7.5 High
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.
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-2025-57354 2026-04-15 6.5 Medium
A vulnerability exists in the 'counterpart' library for Node.js and the browser due to insufficient sanitization of user-controlled input in translation key processing. The affected versions prior to 0.18.6 allow attackers to manipulate the library's translation functionality by supplying maliciously crafted keys containing prototype chain elements (e.g., __proto__ ), leading to prototype pollution. This weakness enables adversaries to inject arbitrary properties into the JavaScript Object prototype through the first parameter of the translate method when combined with specific separator configurations, potentially resulting in denial-of-service conditions or remote code execution in vulnerable applications. The issue arises from the library's failure to properly validate or neutralize special characters in translation key inputs before processing.
