Executive Summary

CVE-2026-45325 is a prototype pollution vulnerability in the @tmlmobilidade/utils package affecting versions before 20260509.0340.15. It exists in the setValueAtPath() function due to unsafe path segments not being blocked. An attacker can exploit this to modify an object's prototype properties, potentially causing unintended behavior or security issues.

Detection Guidance

Detecting prototype pollution vulnerabilities like CVE-2026-45325 requires checking for unsafe path segments in the @tmlmobilidade/utils package. Review application logs for errors related to setValueAtPath() or prototype manipulation. Inspect network traffic for suspicious input patterns targeting object prototypes.

Impact Analysis

This vulnerability allows attackers to manipulate object prototypes, which could lead to arbitrary code execution, denial of service, or data tampering. Since the attack requires no privileges or user interaction, it poses a significant risk if exploited remotely over a network.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by allowing unauthorized modification of object prototypes, which may lead to data integrity issues or unintended code execution. Prototype pollution can be exploited to alter application behavior, potentially exposing or corrupting sensitive data. However, the provided context does not explicitly detail compliance impacts.

Mitigation Strategies

Upgrade @tmlmobilidade/utils to version 20260509.0340.15 or later. If upgrading is not possible, implement input validation to block unsafe path segments like __proto__, constructor, and prototype. Review and sanitize all user-controlled inputs passed to setValueAtPath().
