CVE-2024-57086Public exploitNetwork attack vector

Service interruption via prototype setter path

Published Feb 5, 2025 · Updated Feb 6, 2025

Prototype pollution in node-opcua-alarm-condition before 2.137.0 allows remote attackers to interrupt applications via crafted field paths. fieldsToJson passes attacker-controlled dotted paths such as proto.pollutedKey to setProperty, which assigns through the prototype setter and modifies Object.prototype. An application must pass remote input into fieldsToJson; successful exploitation pollutes the shared prototype and interrupts affected application operation.
