CVE-2026-15302Network attack vector

Unauthenticated file overwrite via unvalidated upload path

Published Jul 10, 2026 · Updated Jul 10, 2026

Path traversal in Repute InfoSystems ARMember 4.0.27 and earlier allows remote attackers to overwrite certain files via X-FILENAME. The upload handling in class.arm_members_activity.php uses the client-controlled header to form a destination path without ensuring that it remains under wp-content/uploads/armember. No credentials or user interaction are required, but the documented consequence is limited to writable file types such as CSS rather than arbitrary code execution.
