Based on this GHSA-mw26-5g2v-hqw3 there is a security vulnerability affecting all version of DeepDiff prior to 8.6.1 which patch that issue. Unfortunately jdiff has as upper limit version 7.
Jdiff needs to be updated, so it can use version 8 in jdiff in order to don't have that vulnerability affecting environments where jdiff is installed :)
