    Action Type Old Value New Value
    Added Description 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.

    Added CVSS V3.1 AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H
