JavaScript vulnerability analysis and mitigation
Overview
CVE-2025-56571 affects Finance.js version 4.1.0, specifically the IRR (Internal Rate of Return) function. The vulnerability was discovered and disclosed on September 30, 2025, and involves a Denial of Service (DoS) condition that can occur through improper handling of the recursion/iteration limit in the depth parameter (NVD, Medium Blog).
Technical details
The vulnerability exists in the IRR function's implementation where the depth parameter is not properly validated. When processing the internal rate of return calculation, the function can enter into excessive recursion or iteration states. The vulnerability has received a CVSS v3.1 Base Score of 7.5 (High) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, indicating a high impact on system availability (NVD, Miggo).
Impact
When exploited, the vulnerability can lead to excessive CPU usage, causing application stalls or crashes. This primarily affects the availability of systems using the Finance.js library, particularly when processing IRR calculations with manipulated depth parameters (NVD, Medium Blog).
