EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.4 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 91% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, a stored cross-site scripting vulnerability in the CCDA document preview allows an attacker who can upload or send a CCDA document to execute arbitrary JavaScript in a clinician's browser session when the document is previewed. The XSL stylesheet sanitizes attributes for all other narrative elements but not for linkHtml, allowing href="javascript:..." and event handler attributes to pass through unchanged. Version 8.0.0.3 patches the issue.
