CVE-2026-114663

Vyper 0.4.0b1 through 0.5.0b1 miscompiles unfoldable constants and omitted default arguments from imported modules, because parseName resolves their names in the using function's scope rather than at declaration. When a contract's parameter, local, or loop variable shares such a name,...

CVE-2026-114663 Vyper 0.4.0b1 through 0.5.0b1 Name Shadowing of Imported Constants and Default Arguments

Vyper 0.4.0b1 through 0.5.0b1 miscompiles unfoldable constants and omitted default arguments from imported modules, because parseName resolves their names in the using function's scope rather than at declaration. When a contract's parameter, local, or loop variable shares such a name,...

CVE-2026-69200: Improperly Controlled Modification of Object Prototype Attributes

node-opcua is an OPC UA implementation for TypeScript and Node.js. Prior to node-opcua-client 2.145.0, the internal fieldsToJson method in packages/node-opcua-client/source/alarmsandconditions/clientalarm.ts directly assigns unsanitized field names and allows a proto.pollutedKey path to modify...

PT-2026-93840

Name of the Vulnerable Software and Affected Versions node-opcua-client versions prior to 2.145.0 Description The fieldsToJson function in the packages/node-opcua-client/source/alarms and conditions/client alarm.ts file directly assigns unsanitized field names. This allows a proto .pollutedKey pa...

CVE-2026-55091

flat-to-nested (NPM, versions ≥1.1.0, ≤1.1.1) is vulnerable to prototype pollution (CWE-1321) in FlatToNested.prototype.convert (index.js). The function uses attacker-controlled id and parent field values directly as keys in plain objects, so a value of "__proto__" resolves via the prototype chai...

CVE-2026-55091 flat-to-nested: Prototype pollution in flat-to-nested convert() via __proto__ parent/id key

flat-to-nested converts a hierarchy from a flat representation to a nested representation. Prior to 1.1.2, FlatToNested.prototype.convert in index.js uses attacker-influenced id and parent record fields directly as keys in the plain temp and pendingChildOf objects. When parent or id is proto,...

EUVD-2026-77579

Yayson is a library for serializing and reading JSON API data in JavaScript. Prior to 4.3.0, Store and LegacyStore use attacker-controlled JSON:API type, id, and relationship names as keys in plain-object lookup tables in src/yayson/store.ts and src/yayson/legacy-store.ts. A document whose type i...

CVE-2026-55091: Improperly Controlled Modification of Dynamically-Determined Object Attributes

flat-to-nested converts a hierarchy from a flat representation to a nested representation. Prior to 1.1.2, FlatToNested.prototype.convert in index.js uses attacker-influenced id and parent record fields directly as keys in the plain temp and pendingChildOf objects. When parent or id is proto,...

PT-2026-90549

Summary Store/LegacyStore key internal lookup tables by the type, id, and relationship names from a JSON:API document. Because these were plain objects, a document with type: " proto " writes onto Object.prototype, polluting every object in the process. Severity Suggested CVSS v3.1...

PT-2026-68805

Name of the Vulnerable Software and Affected Versions Mermaid versions 11.5.0 through 11.16.0 Description Mermaid Architecture Diagrams are subject to prototype pollution, a condition where an attacker can manipulate the Object.prototype of the JavaScript environment. This occurs when a diagram...

PT-2026-68932

Rendering an untrusted architecture-beta diagram lets the diagram author write an arbitrary property with the value horizontal or vertical onto Object.prototype. A group id of proto is accepted as a valid parent. Impact Any code in the same realm that reads a property of that name from an arbitra...

PT-2026-32616

Summary @stablelib/cbor decodes CBOR maps into ordinary JavaScript objects and assigns attacker-controlled keys directly onto those objects. A CBOR map key named proto therefore changes the prototype of the decoded object instead of becoming an ordinary data property. Details The decoder builds m...

PT-2017-6772

Name of the Vulnerable Software and Affected Versions B.A.S C2Box versions prior to 4.0.0 r19171 Description The issue relies on client-side validation, allowing remote attackers to corrupt the business logic by submitting a negative value in an overdraft. Recommendations For versions prior to...

CVE-2015-4626: Undefined Security Weakness

B.A.S C2Box before 4.0.0 r19171 relies on client-side validation, which allows remote attackers to "corrupt the business logic" via a negative value in an overdraft...
