Comment 1 Pedro Sampaio 2020-09-16 20:26:19 UTC 
Created dojo tracking bugs for this issue:

Affects: epel-6 [bug 1879725]
Affects: epel-7 [bug 1879726]
Comment 2 Todd Cullum 2020-09-17 18:48:10 UTC 
Statement:

ipa as shipped with Red Hat Enterprise Linux 5, 6, 7, and 8 is not affected by this flaw because it does not use the dijit functionality of dojo.
Comment 3 Todd Cullum 2020-09-17 18:56:35 UTC 
Flaw summary:

Editing a link description in dijit LinkDialog could allow for parsing of < character and lead to cross-site scripting. The patch introduces a filter which is set to replace < with &lt by default.
