OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the `xl()` translation function returns unescaped strings. While wrapper functions exist for escaping in different contexts (`xlt()` for HTML, `xla()` for attributes, `xlj()` for JavaScript), there are places in the codebase where `xl()` output is used directly without escaping. If an attacker could insert malicious content into the translation database, these unescaped outputs could lead to XSS. Version 8.0.0 fixes the issue.
