CVE-2026-21443
No affected components available
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.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges.
Limited exploitation activity has been observed. Close monitoring and planned remediation are recommended.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
