Title
Welcart e-Commerce Plugin paymentESCOTT.main.class.php error_page_message cross site scripting
Summary
A vulnerability was identified in Welcart e-Commerce Plugin up to 2.12.6 on WordPress. This affects the function ESCOTT_MAIN::error_page_message of the file classes/paymentESCOTT.main.class.php. Such manipulation of the argument ResponseCd leads to cross site scripting. The attack can be launched remotely. The exploit is publicly available and might be used. Upgrading to version 2.12.7 mitigates this issue. It is recommended to upgrade the affected component. The value is now escaped with esc_html() before output. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
