Comment 1 Guilherme de Almeida Suckevicz 2021-12-22 17:42:45 UTC

Created dojo tracking bugs for this issue:

Affects: epel-all [bug 2035013]

Comment 2 Garrett Tucker 2021-12-22 18:55:36 UTC

RHEL 7 IPA is unaffected. While IPA does make use of Dojo, it is limited in its scope and does not use the affected setObject function. While it is possible to create a plugin / extension for ipa that could make use of the setObject function in dojo, this would require privileges that are already escalated to that of an ipa admin at minimum which would provide more control than exploitation of the flaw.
