The Blaze Online eParcel for WooCommerce plugin suffers from a reflected cross-site scripting vulnerability due to improper input neutralization during web page generation. This flaw affects all versions up to 1.3.3 and allows attackers to inject malicious scripts that execute when a user interacts with a crafted link or input. The CVSS score is 7.1 (high), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. No patch or vendor advisory is currently available, and the product is not a cloud service.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the victim's browser session, potentially leading to theft of sensitive information, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability. However, exploitation requires user interaction, and no known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with untrusted inputs and links related to the Blaze Online eParcel plugin. Monitor vendor channels for updates and apply patches promptly once released.
