Upgrade Amazon-Linux:2 mod_auth_openidc-debuginfo to version 0:1.8.8-5.amzn2 or higher.
This issue was patched in ALAS2-2019-1329.
NVD Description
Note: Versions mentioned in the description apply only to the upstream mod_auth_openidc-debuginfo package and not the mod_auth_openidc-debuginfo package as distributed by Amazon-Linux.
See How to fix? for Amazon-Linux:2 relevant fixed versions and status.
The "OpenID Connect Relying Party and OAuth 2.0 Resource Server" (aka mod_auth_openidc) module before 2.1.6 for the Apache HTTP Server does not skip OIDC_CLAIM_ and OIDCAuthNHeader headers in an "AuthType oauth20" configuration, which allows remote attackers to bypass authentication via crafted HTTP traffic.
