CVE-2026-41139: CWE-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes in josdejong mathjs
Math. js versions from 13. 1. 0 up to but not including 15. 2. 0 contain a vulnerability that allows arbitrary JavaScript execution via its expression parser. This issue is due to improperly controlled modification of dynamically-determined object attributes (CWE-915). The vulnerability has been patched in version 15. 2. 0.
AI Analysis
Technical Summary
CVE-2026-41139 affects the mathjs library for JavaScript and Node.js, specifically versions >=13.1.0 and <15.2.0. The vulnerability arises from the expression parser allowing arbitrary JavaScript execution due to improper control over modification of dynamically-determined object attributes (CWE-915). This can lead to full compromise of confidentiality, integrity, and availability of affected systems. The issue has been addressed and patched in mathjs version 15.2.0.
Potential Impact
Successful exploitation allows an attacker with at least low privileges (PR:L) and no user interaction (UI:N) to execute arbitrary JavaScript code remotely (AV:N). This can result in complete compromise of the affected system's confidentiality, integrity, and availability. The vulnerability is rated high severity with a CVSS score of 8.8.
Mitigation Recommendations
Upgrade mathjs to version 15.2.0 or later, where this vulnerability has been patched. No other official remediation or temporary fixes are indicated. Patch status is confirmed by the vendor advisory stating the issue is fixed in version 15.2.0.
