CVE-2026-2699 is a critical authentication bypass vulnerability in customer-managed Progress ShareFile Storage Zones Controller 5.x, affecting versions prior to 5.12.4. The flaw is caused by an Execution After Redirect condition in the ASP.NET-based administrative interface, specifically the Admin.aspx configuration page, where the application issues an HTTP redirect to the login page but continues executing page logic instead of terminating processing. As a result, an unauthenticated remote attacker can access restricted configuration functionality and interact with administrative features intended to require authentication. Exposure of these configuration pages allows modification of storage zone settings and security-sensitive parameters, and it can be chained with CVE-2026-2701 to achieve unauthenticated remote code execution on exposed on-premises servers. Progress stated that ShareFile Storage Zones Controller 6.x is not affected.
