CVE-2026-118047
The Falang multilanguage for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'falang_term[<taxonomy>][<locale>][<field>] (via order[] driving wp_update_term)' parameter in all versions up to, and including, 1.4.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit is made reliable because the required 'falang' nonce is disclosed to any logged-in user through the equally unprotected wp_ajax_falang_menu_translation handler, requiring no elevated access to obtain.

Remediation & validation
- Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
- Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
- Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
- Validate the remediation with a version check and vulnerability rescan, then retain change evidence.
No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
