CVSS

Base score: 8.8
Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.29 %
Percentile among all scored CVEs: 20
Score date: 10/21/2026

ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

ExploitationT1203 Exploitation for Client Executionexecution85 %

El vector UI:R exige interacción de un usuario distinto del atacante, por lo que la explotación es T1203. El texto solo menciona 'takeover' sin mecanismo concreto, así que no se asignan impactos.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
