FUXA Unauthenticated Exposure of Plaintext Database Credentials

CVE-2026-25751GHSA-c5gq-4h56-4mmx

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (fuxa-server 1.2.10), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Description An information disclosure vulnerability in FUXA allows an unauthenticated, remote attacker to retrieve sensitive administrative database credentials. This affects FUXA through version 1.2.9. This issue has been patched in FUXA version 1.2.10. Impact This affects all deployments, including those with runtime.settings.secureEnabled set to true. Exploitation allows an unauthenticated, remote attacker to obtain the full system configuration, including administrative 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. Patches This issue has been patched in FUXA version 1.2.10. Users are strongly encouraged to update to the latest available release.

# Patch Next advisory brief: CVE-2026-25751

Advisory: FUXA Unauthenticated Exposure of Plaintext Database Credentials
IDs: CVE-2026-25751, GHSA-c5gq-4h56-4mmx
Record: https://patchnext.com/advisories/cve-2026-25751 (revision 4, source checked 26 Oct 2026, 12:42 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: fuxa-server 1.2.10. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm fuxa-server: affected <= 1.2.9; fixed in 1.2.10

## Suggested inspection (read-only)
- `npm ls fuxa-server --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on fuxa-server.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-c5gq-4h56-4mmx (GitHub-reviewed advisory GHSA-c5gq-4h56-4mmx lists affected ranges: npm fuxa-server >=0 <=1.2.9)
- Verified: https://osv.dev/vulnerability/GHSA-c5gq-4h56-4mmx (OSV record GHSA-c5gq-4h56-4mmx lists affected ranges: npm fuxa-server >=0 <1.2.10 (fixed))
