Detailsinfo

A vulnerability was found in messageformat up to 3.0.0. It has been classified as problematic. This affects some unknown processing of the component Runtime Component. The manipulation with an unknown input leads to a prototype pollution vulnerability. CWE is classifying the issue as CWE-1321. The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype. The impact remains unknown. The summary by CVE is:

The Runtime components of messageformat package for Node.js before 3.0.2 contain a prototype pollution vulnerability. Due to insufficient validation of nested message keys during the processing of message data, an attacker can manipulate the prototype chain of JavaScript objects by providing specially crafted input. This can result in the injection of arbitrary properties into the Object.prototype, potentially leading to denial of service conditions or unexpected application behavior. The vulnerability allows attackers to alter the prototype of base objects, impacting all subsequent object instances throughout the application's lifecycle.

It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2025-57353 since 08/17/2025. Technical details are unknown but a public exploit is available. The attack technique deployed by this issue is T1059 according to MITRE ATT&CK.

The exploit is shared for download at github.com. It is declared as proof-of-concept.
