CVE-2021-25921

Estado: ModificadaMedia (5.4)—

In OpenEMR, versions 2.7.3-rc1 to 6.0.0 are vulnerable to Stored Cross-Site-Scripting (XSS) due to user input not being validated properly in the `Allergies` section. An attacker could lure an admin to enter a malicious payload and by that initiate the exploit.

CVSS

Probabilidad de explotación (EPSS)

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).
