CVE-2020-5219

Estado: ModificadaAlta (8.8)—

Angular Expressions before version 1.0.1 has a remote code execution vulnerability if you call expressions.compile(userControlledInput) where userControlledInput is text that comes from user input. If running angular-expressions in the browser, an attacker could run any browser script when the application code calls expressions.compile(userControlledInput). If running angular-expressions on the server, an attacker could run any Javascript expression, thus gaining Remote Code Execution.

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).
