What is CVE-2026-103325?

The TiendaCrypto plugin for WooCommerce, up to version 1.2.1, suffers from a significant security flaw where the authenticity of payment webhook requests is not properly validated. This is due to an empty key used for verifying request signatures, rendering the system vulnerable to unauthenticated attackers. As a result, malicious users can manipulate webhook notifications and incorrectly mark WooCommerce orders as paid, potentially leading to significant financial fraud and undermining the integrity of order processing on affected web servers.

Affected Version(s)

TiendaCrypto para WooCommerce 1.0.1 <= 1.2.1

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.
