CVE-2026-39079Public exploitNetwork attack vector

Unauthenticated sensitive-data disclosure via public XML logs

Published May 18, 2026 · Updated May 18, 2026

Information disclosure in Agence Web 360 UPS Shipping Module 2.4.0 and earlier allows remote attackers to read sensitive XML logs. UPSBaseApi.php writes full SOAP requests and responses, including UPS credentials and customer data, to timestamp-named XML files in a web-accessible logs directory without access controls. No authentication or user interaction is required; predictable filenames expose merchant credentials and customer PII but provide no write access.
