What is CVE-2026-5936?

A security flaw in Foxit software allows attackers to manipulate server-side HTTP requests via a specially crafted URL. This capability permits the server to send requests to arbitrary external destinations. Attackers may exploit this to investigate internal network services, gain unintended access to previously restricted endpoints, such as cloud metadata services, or circumvent network access controls. These actions can lead to unauthorized information disclosure and pose risks to the security of the overall internal environment.
