Summary

OpenEMR before 8.5.0 contains an SQL injection vulnerability in SLEOB::slInvoiceNumber() in src/Billing/SLEOB.php, which concatenates the CLP01 claim identifier from uploaded X12 835 ERA files into a query without escaping or parameter binding. Authenticated users with billing permissions, or a malicious payer whose ERA file a clerk uploads, can execute arbitrary SQL to read any table, including users_secure password hashes, and modify data.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of openemr/openemr published their own advisory on GitHub. Reviewed sources take precedence over it.
