CVE-2025-54221

Status: AnalyzedHigh (7.8)—

InCopy versions 20.4, 19.5.4 and earlier are affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

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 requerida) y descripción explícita de apertura de archivo malicioso indica ejecución en el cliente (T1203). CWE-787 (buffer overflow) con arbitrary code execution sugiere T1059 como impacto.

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