CVSS
- Base score
- 7.5
- Version
- 3.1
- Vector
- CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days
- 0.60 %
- Percentile among all scored CVEs
- 48
- Score date
- 10/20/2026
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 Interpreterexecution80 %
El vector CVSS indica UI:R (requiere interacción del usuario), así que la explotación es T1203; el texto habla de ejecución de código sin nombrar un intérprete, por lo que se usa T1059.
Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
