CVE-2021-42026

Estado: ModificadaMedia (4.3)—

A vulnerability has been identified in Mendix Applications using Mendix 8 (All versions < V8.18.13), Mendix Applications using Mendix 9 (All versions < V9.6.2). Applications built with affected versions of Mendix Studio Pro do not properly control read access for certain client actions. This could allow authenticated attackers to retrieve the changedDate attribute of arbitrary objects, even when they don't have read access to them.

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).
