Openemr: Files or Directories Accessible to External Parties

CVE-2023-22974 is a high-severity files or directories accessible to external parties vulnerability in Openemr from Open-emr, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 7.0.0 as the first without the flaw, so updating Openemr to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.89% chance of exploitation within 30 days, higher than 80% of scored CVEs.
