CVE-2026-14289
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe FacturaONE para WooCommerce con VeriFactu WordPress plugin before 5.37 does not authenticate one of its request handlers, whose only protection is derived from a cryptographic key that is empty in the default, unconfigured state, allowing unauthenticated attackers to write an arbitrary file into a web-accessible directory and achieve remote code execution.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisThe application evaluates attacker-influenced input as code, handing them a way to run logic inside the process. Depending on the runtime this can escalate directly to remote code execution. Remediation means removing dynamic evaluation of untrusted input and replacing it with safe, data-driven alternatives.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped5.37
- Update the FacturaONE para WooCommerce con VeriFactu WordPress plugin to version 5.37 or later through the WordPress admin dashboard (Plugins > Updates) or via wp-cli: wp plugin update facturaone-para-woocommerce-con-verifactu
- After updating, navigate to the plugin settings and configure a non-empty cryptographic key as recommended by the plugin documentation to ensure the protection mechanism is properly enabled
- Verify the update was successful by checking the plugins page and confirming the version number
- Review the plugin's authentication settings to ensure the cryptographic key is properly configured and not left at default empty values
- Monitor for any suspicious files in web-accessible directories (wp-content/uploads, etc.) that may have been created during any prior exploitation

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
Free. We build fixes in the order the community asks for them — and we’ll tell you the moment this one lands.
We develop and verify an original fix where the vendor hasn’t, from $3,550. Deployed to your staging first — never straight to production.
