Update the Electronic Signature Add-on for Fluent Forms to 2.0.6
October 19, 2026
CVE-2026-110383 concerns the Electronic Signature Add-on for Fluent Forms, not every Fluent Forms installation. Versions through 2.0.5 are in scope; 2.0.6 is identified by the CNA as unaffected. The CNA reports an unauthorized access-control bypass that may expose sensitive contract-related information. Exploitation is not established.
Confirm the exact add-on
Start by distinguishing the Electronic Signature Add-on for Fluent Forms from Fluent Forms core and other signature products. Inventory the add-on’s installed version, whether it is active, the WordPress and PHP versions, connected form workflows, and any storage or notification dependencies. Do not infer that a site running only Fluent Forms core is affected.
Create a verified backup and, where possible, stage the same configuration using fictional forms, fictional signers, and non-sensitive documents. Capture the existing version and test expectations before making changes. This establishes a maintenance record; it does not establish an installed vulnerable version, exposure, or compromise.
- Affected range: through 2.0.5.
- Fixed floor: 2.0.6.
- CNA status for 2.0.6: unaffected.
- Reported exploitation: not established.
Update without broadening the scope
Use the standard WordPress plugin update mechanism to install version 2.0.6 or a later release compatible with the site. Review the add-on’s documented platform requirements and test integration behavior in staging first. Update the electronic-signature add-on itself; do not describe the change as an update for all Fluent Forms installations.
Confirm after updating that the intended add-on is still active and that its recorded version meets or exceeds 2.0.6. If a rollback is required for service continuity, document it clearly: restoring an older backup may reintroduce the version range under review. Build a compatibility plan rather than leaving the add-on indefinitely below the repair floor.
Run ordinary signature workflow checks
With synthetic staging data, submit a representative test form, complete the legitimate signature-related workflow supported by the site, verify expected confirmation notices, and check that authorized staff can locate the resulting test record. Also verify that required fields, retention behavior, and intended downstream notifications still work. Avoid testing with real signatures, client documents, or sensitive personal data.
Check the WordPress error log and the add-on’s ordinary activity records for update-related errors. Record results, timestamps, the test form name, and the installed version. These checks validate expected business behavior, not the absence of all security risk.
Review relevant evidence carefully
No exploitation evidence is available here, so avoid guarantees about attack history. Review available account changes, administrator activity, form and signature record access, configuration changes, and hosting alerts for unexplained events during the period the affected add-on version may have been present. Retain records according to the organization’s privacy and incident policies.
If findings suggest unauthorized access, preserve evidence and follow the site’s response process. Updating to 2.0.6 addresses the reported version condition but does not prove that prior records were untouched.
