FUXA: Insertion of Sensitive Information Into Sent Data
CVE-2026-47717 is a high-severity insertion of sensitive information into sent data vulnerability in FUXA from Frangoteam, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected FUXA versions: = 1.3.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.38% chance of exploitation within 30 days, higher than 72% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of FUXA you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In fuxa-server version 1.3.0, the GET /api/project endpoint exposes sensitive project configuration data to guest-context requests even when secureEnabled is enabled. Version 1.3.1 fixes the issue.

The underlying weakness: Insertion of Sensitive Information Into Sent Data
The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.
How developers prevent this class of flaw
- Specify which data in the software should be regarded as sensitive. Consider which types of users should have access to which types of data.
- Ensure that any possibly sensitive data specified in the requirements is verified with designers to ensure that it is either a calculated risk or mitigated elsewhere. Any information that is not necessary to the functionality should be removed in order to lower both the overhead and the possibility of security sensitive data being sent.
- Setup default error messages so that unexpected errors do not disclose sensitive information.
