Object prototype modification via inherited path traversal
Published Apr 15, 2022 · Updated Sep 17, 2024
Prototype pollution in Springtree madlib-object-utils before 0.1.8 allows attackers to modify object prototypes via a crafted property path. The setValue method splits a dot-delimited path and traverses inherited properties without requiring each segment to be an own property, allowing paths such as this.constructor.prototype to reach Object.prototype. Exploitation requires a consuming application to pass an attacker-controlled path to the library; successful use poisons properties inherited by other objects in that process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
