CVE-2026-9960

Status: AnalyzedHigh (7.5)—

Integer overflow in PDFium in Google Chrome prior to 148.0.7778.216 allowed a remote attacker who had compromised the renderer process to execute arbitrary code inside a sandbox via a crafted font file. (Chromium security severity: High)

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 CVSS con UI:R (interacción del usuario abriendo/visualizando PDF) indica T1203. El atacante requiere compromiso previo del renderer, logra ejecución de código arbitrario en sandbox (T1059) con potencial escalada local (T1068).

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