NO FIX YET · SEE WHAT TO DO
OpenEMR before 8.3.0 has a path traversal flaw in its billing EOB processing script, where unsanitized eraname values let ../ sequences escape the intended directory. An logged-in user can write report files anywhere the web server can write and read arbitrary .edi file contents back out.

It checks your repository and tells you if you’re affected, with the fix.
OpenEMR installations before 8.3.0 with user accounts that can reach the billing EOB processing feature. Per the description, attackers without billing privileges can still exploit it by injecting ../ sequences. Self-hosted deployments are the ones to look at; sites that cannot reach the billing page from user accounts have less exposure.
