CVE-2024-21632

Estado: ModificadaCrítica (9.8)—

omniauth-microsoft_graph provides an Omniauth strategy for the Microsoft Graph API. Prior to versions 2.0.0, the implementation did not validate the legitimacy of the `email` attribute of the user nor did it give/document an option to do so, making it susceptible to nOAuth misconfiguration in cases when the `email` is used as a trusted user identifier. This could lead to account takeover. Version 2.0.0 contains a fix for this issue.

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).
