AnalysisAIv1 – Jul 27, 2026

Remote code execution in FacturaONE for WooCommerce plugin before version 5.37 allows unauthenticated attackers to write arbitrary files to a web-accessible directory and achieve code execution, because a request handler relies on an empty default cryptographic key and lacks authentication. Public exploit code is available.

DescriptionCVE.org

The 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.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
