Summary
Apache APISIX: Identity spoofing issue in APISIX opa plugin
Details

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.
