What is CVE-2026-103323?
The Epos Now integration for WooCommerce WordPress plugin versions prior to 4.11.2 lacks sufficient authorization checks on a critical REST API endpoint. This vulnerability allows unauthenticated users to access sensitive information, including details of scheduled background tasks and their parameters. Notably, this may expose order identifiers and, if WooCommerce's deferred emails feature is active, the plaintext passwords of newly registered users, posing a significant risk to user privacy and site security.
Affected Version(s)
Integration for Epos Now and WooCommerce 4.6.0 < 4.11.2
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
