Authentication Bypass by Spoofing vulnerability in opa plugin.
LOW 2.3EPSS 0.57%
Does this matter?
Lower severity and a low EPSS score (0.57%). Track it; it rarely justifies an emergency change on its own.
Description
Authentication Bypass by Spoofing vulnerability in opa plugin. An attacker could relay spoofed identity headers to upstream capitalising on non-default configuration in opa plugin. This could allow the attacker to assume higher privileges on the upstream service. This issue affects Apache APISIX: from 3.5.0 through 3.16.0. Users are recommended to upgrade to version 3.17.0, which fixes the issue.
