Exploitation probability (EPSS)
FIRST hasn't scored this CVE yet (usual for very recent or rejected CVEs).
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.
- Exploitation
T1203Exploitation for Client Executionexecution85 % - Primary impact
T1059Command and Scripting Interpreterexecution70 %
El vector CVSS incluye UI:R, por lo que la explotación es T1203 pese a AV:N; el texto dice 'execute code' sin intérprete concreto, así que el impacto es T1059 genérico.
Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
