CVE-2026-3207 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Tibco Bpm Enterprise. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 15.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-17 (Remote Access).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

CM-6 Configuration Settings good match

prevent

Establishes and enforces secure configuration settings for the JMX component to require authentication, directly mitigating the configuration issue enabling unauthorized access.

AC-14 Permitted Actions Without Identification or Authentication good match

prevent

Explicitly authorizes and limits any permitted actions without identification or authentication, preventing unauthorized use of critical JMX functions.

AC-17 Remote Access good match

prevent

Manages and restricts remote access mechanisms like JMX to prevent network-based unauthorized exploitation.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

Missing authentication on the exposed JMX management interface (CWE-306) directly enables remote unauthenticated exploitation of a public-facing application, resulting in full compromise of the TIBCO BPM instance.

NVD Description

Configuration issue in Java Management Extensions (JMX) in TIBCO BPM Enterprise version 4.x allows unauthorised access.

Deeper analysisAI

CVE-2026-3207 is a configuration issue in the Java Management Extensions (JMX) component of TIBCO BPM Enterprise version 4.x that allows unauthorized access. Published on 2026-03-17, the vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is linked to CWE-306 (Missing Authentication for Critical Function).

The vulnerability enables exploitation over the network with low attack complexity, requiring no privileges, user interaction, or scope changes. A successful attack can result in high impacts to confidentiality, integrity, and availability, potentially allowing an unauthenticated remote attacker to fully compromise the affected TIBCO BPM Enterprise instance.
