Overview
The vulnerability designated as CVE-2025-57325 is a Prototype Pollution flaw found in the rollbar JavaScript package, specifically version 2.26.4 and earlier. The vulnerability affects developers and users of applications that use this package and could potentially lead to system compromise or data leakage. It’s crucial to understand and address this vulnerability due to its high severity score and its potential to cause a denial of service.
Vulnerability Summary
CVE ID: CVE-2025-57325
Severity: High (CVSS: 7.5)
Attack Vector: Remote
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage
Affected Products
A new way to communicate
Ameeba Chat is built on encrypted identity, not personal profiles.
Message, call, share files, and coordinate with identities kept separate.
- • Encrypted identity
- • Ameeba Chat authenticates access
- • Aliases and categories
- • End-to-end encrypted chat, calls, and files
- • Secure notes for sensitive information
Private communication, rethought.

How the Exploit Works
The vulnerability lies within the utility.set function of the rollbar package. An attacker can inject properties on Object.prototype by supplying a specially crafted payload. This Prototype Pollution attack can lead to unexpected behaviour in the application, including a Denial of Service (DoS) condition and potentially further exploitation leading to system compromise or data leakage.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. An attacker could send a POST request with a malicious JSON payload to a vulnerable endpoint:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "__proto__": { "polluted": "Prototype Polluted!" } }In this example, if the application uses the rollbar package to handle this request, the polluted property would be added to all objects in the application, resulting in unexpected behaviour or potential system compromise.
Mitigation Guidance
Users of the rollbar package are advised to apply the vendor-supplied patch to mitigate this vulnerability. If a patch cannot be applied immediately, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, this does not replace the need for patching the vulnerable software. It is critical to keep all software up-to-date to protect against known vulnerabilities.
