CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

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

Vector AV:N/PR:N/UI:N indica explotación remota sin privilegios (T1190). CWE-22 (path traversal) permite escritura arbitraria de archivos (T1565.001) en Safari/iOS/macOS. La pista sugiere T1005 pero el texto explicita 'write arbitrary files', no lectura.

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