CVE-2026-25751
Published: 06 February 2026
Summary
CVE-2026-25751 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Frangoteam Fuxa. Its CVSS base score is 9.1 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 18.3th 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-3 (Access Enforcement) and IA-5 (Authenticator Management).
Deeper analysis
CVE-2026-25751 is an information disclosure vulnerability in FUXA, an open-source web-based Process Visualization (SCADA/HMI/Dashboard) software. The flaw allows an unauthenticated remote attacker to retrieve sensitive administrative database credentials, exposing the full system configuration, including credentials for the InfluxDB database. It affects all versions of FUXA through 1.2.9 and has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), linked to CWE-306 (Missing Authentication for Critical Function) and CWE-312 (Cleartext Storage of Sensitive Information).
An unauthenticated attacker with network access can exploit this vulnerability remotely with low complexity, without requiring user interaction or privileges. Successful exploitation grants the full system configuration and InfluxDB administrative credentials, enabling direct authentication to the database service. This allows the attacker to read, modify, or delete all historical process data, or conduct a denial-of-service by corrupting the database.
The issue has been addressed in FUXA version 1.2.10, as detailed in the project's GitHub release notes (https://github.com/frangoteam/FUXA/releases/tag/v1.2.10) and security advisory (https://github.com/frangoteam/FUXA/security/advisories/GHSA-c5gq-4h56-4mmx). Security practitioners should upgrade to the patched version and review exposed FUXA instances for potential credential compromise.

Vulnerability details
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. An information disclosure vulnerability in FUXA allows an unauthenticated, remote attacker to retrieve sensitive administrative database credentials.

for the InfluxDB database. Possession of these credentials may allow an attacker to authenticate directly to the database service, enabling them to read, modify, or delete all historical process data, or perform a Denial of Service by corrupting the database. This affects FUXA through version 1.2.9. This issue has been patched in FUXA version 1.2.10.

Directly enforces authentication before allowing access to the sensitive administrative credential retrieval function that the CVE exploits.
Requires cryptographic protection of sensitive information (the InfluxDB administrative credentials) at rest, directly mitigating the CWE-312 cleartext storage aspect.
Mandates secure authenticator management practices that would prevent exposure of database credentials via the unauthenticated endpoint.
