CVE-2021-25922
Estado: ModificadaMedia (6.1)—
In OpenEMR, versions 4.2.0 to 6.0.0 are vulnerable to Reflected Cross-Site-Scripting (XSS) due to user input not being validated properly. An attacker could trick a user to click on a malicious url and execute malicious code.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
- Puntuación base: 6.1
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.84%
- Percentil entre todas las CVEs puntuadas: 57
- Fecha de la puntuación: 7/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
