CVE-2026-5189

Status: AnalyzedCritical (9.2)—

CWE-798: Use of Hard-coded Credentials in Sonatype Nexus Repository Manager versions 3.0.0 through 3.70.5 allows an unauthenticated attacker with network access to gain unauthorized read/write access to the internal database and execute arbitrary OS commands as the Nexus process user. Exploitation requires the non-default nexus.orient.binaryListenerEnabled=true configuration to be enabled.

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.

Vulnerabilidad de credenciales hardcodeadas (CWE-798) en Nexus expuesto en red (AV:N, PR:N, UI:N). Permite acceso no autenticado a BD interna y ejecución de comandos OS como usuario Nexus. Requiere configuración no estándar pero explotable remotamente.

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