CVE-2025-6504: Progress Hybrid Data Pipeline

High severity, CVSS 8.4. EPSS: 0.2% chance of exploitation in the next 30 days.

In HDP Server versions below 4.6.2.2978 on Linux, unauthorized access could occur via IP spoofing using the X-Forwarded-For header.  Since XFF is a client-controlled header, it could be spoofed, allowing unauthorized access if the spoofed IP matched a whitelisted range. This vulnerability could be exploited to bypass IP restrictions, though valid user credentials would still be required for resource access.

Affected products

• Progress Hybrid Data Pipeline: before 4.6.2.2978 (fixed in 4.6.2.2978)
