Title

Joomla Extension - j2commerce.com - Missing CSRF protection on cart, checkout and myprofile controllers in J2Store 1.0.0-3.3.2, 4.0.0-4.0.22, 4.1.0-4.1.7

Summary

Joomla Extension - j2commerce.com - Missing CSRF protection on cart, checkout and myprofile controllers in J2Store 1.0.0-3.3.2, 4.0.0-4.0.22, 4.1.0-4.1.7 - A forged request riding a victim's active checkout session could silently overwrite the billing or shipping address before order confirmation — the most consequential sub-case, since it opens the door to redirecting a paid order's goods to an attacker-controlled address — or tamper with a saved profile address via `saveAddress()`. As before, each forged request executes with only the victim's own session privileges, so there is no cross-account data access.

GHSA-H4FR-VQPQ-MPM6

Vulnerability from github – Published: 2026-09-15 21:31 – Updated: 2026-09-15 21:31

Details

Joomla Extension - j2commerce.com - Missing CSRF protection on cart, checkout and myprofile controllers in J2Store 1.0.0-3.3.2, 4.0.0-4.0.22, 4.1.0-4.1.7 - A forged request riding a victim's active checkout session could silently overwrite the billing or shipping address before order confirmation — the most consequential sub-case, since it opens the door to redirecting a paid order's goods to an attacker-controlled address — or tamper with a saved profile address via saveAddress(). As before, each forged request executes with only the victim's own session privileges, so there is no cross-account data access.

Severity

7.1 (High)


                  
                    CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N

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.
