Jan Høydahl created SOLR-18213:
----------------------------------

             Summary: Improve magic-byte filetype detection
                 Key: SOLR-18213
                 URL: https://issues.apache.org/jira/browse/SOLR-18213
             Project: Solr
          Issue Type: Improvement
            Reporter: Jan Høydahl


Today solr uses library {{com.j256.simplemagic:simplemagic}} to detect file types uploaded with various Solr APIs, to block executable and disallowed file types. That library is Latest has had no release in 4+ years so is likely stale.

We can re-implement the needed checks and get rid of the library.
