CVE-2026-4101

Status: AnalyzedCritical (9.8)—

IBM Verify Identity Access Container 11.0 through 11.0.2 and IBM Security Verify Access Container 10.0 through 10.0.9.1 and IBM Verify Identity Access 11.0 through 11.0.2 and IBM Security Verify Access 10.0 through 10.0.9.1 under certain load conditions could allow an attacker to bypass authentication mechanisms and gain unauthorized access to the application.

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:3.1/AV:N/AC:L/PR:N/UI:N indica explotación remota sin privilegios ni interacción (T1190). CWE-287 (autenticación deficiente) bajo ciertas condiciones de carga permite bypass de autenticación y acceso no autorizado (T1078).

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