NVD Description

Note: Versions mentioned in the description apply only to the upstream eap8-jackson-dataformats-text package and not the eap8-jackson-dataformats-text package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

A flaw was found in EAP's Elytron. An EAP application whose security domain is backed by an Elytron token-realm with oauth2-introspection would allow parameter substitution due to missing URL encoding.
