Vulnerability Details

CVE ID: CVE-2025-41670
Severity: HIGH
CVSS Score: 7.8
Published: May 27, 2026
Weakness (CWE): CWE-427

Technical Description

A local user with low privileges may be able to influence the behavior of a privileged system service by manipulating configuration or application-related files located in user-writable areas of the filesystem. The affected service processes data from locations that are not sufficiently protected against modification by low-privileged users. As the service runs with elevated privileges, successful exploitation may result in a local privilege escalation.

Recommended Action

No official patch is available yet. Until one is released:

1. Monitor the official NVD page and vendor channels for patch announcements.
2. Restrict access to the affected system or service where possible.
3. Apply network-level mitigations such as firewall rules or WAF policies.
4. Enable logging and alerting for anomalous activity related to this vulnerability.
5. Review your incident response plan in case of active exploitation.
