Detection & mitigation playbook

Vendor / appliance

  1. Detect

    Inventory every Epsiloncool WP Fast Total Search deployment and check each version against the affected-products list above.

  2. Remediation status

    The records we use list no fixed version for CVE-2026-57683 (versions up to 1.80.280 are affected). Check the Epsiloncool WP Fast Total Search advisory for a patched release, and apply the workarounds below until you can upgrade.

  3. Mitigate without a patch

    Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
