IPA (Japan) issued an advisory for EC-CUBE, an open-source e-commerce site-building platform developed by EC-CUBE Co., Ltd. The flaw is a cross-site scripting (XSS) vulnerability in the product's administrative screen: an attacker can inject a script into specific input fields on an EC site built with the vulnerable product, causing arbitrary script execution in the browser of the site's administrator when they view the affected page.
The developer has confirmed that attacks exploiting this vulnerability have already been observed in the wild, prompting IPA to urge site operators to apply developer-provided updates or hotfix patches as soon as possible. CVSS v3 base score is rated 7.1 (important) and CVSS v2 at 6.8 (warning). No specific affected version list or patch details were included in the source text beyond the recommendation to update.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
