ATT&CK techniques

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

UI:R y AV:N apuntan a T1203; el texto solo cita bypass de site isolation con C:L, sin credenciales ni cuentas, así que descarto T1078 de la pista.

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