CVE-2026-5936: Foxit PDF Services API

Critical severity, CVSS 9.8. EPSS: 0.3% chance of exploitation in the next 30 days.

An attacker can control a server-side HTTP request by supplying a crafted URL, causing the server to initiate requests to arbitrary destinations. This behavior may be exploited to probe internal network services, access otherwise unreachable endpoints (e.g., cloud metadata services), or bypass network access controls, potentially leading to sensitive information disclosure and further compromise of the internal environment.
