CERT-FR issued an advisory covering multiple vulnerabilities in Moodle, a widely used open-source learning management system deployed by educational institutions worldwide. The flaws allow an attacker to perform SQL injection (SQLi) and to bypass security policy controls. Affected versions include Moodle 5.0.x prior to 5.0.10, 5.1.x prior to 5.1.7, 5.2.x prior to 5.2.3, and all versions prior to 4.5.14.
No evidence of in-the-wild exploitation is mentioned in the advisory. CERT-FR directs administrators to the official Moodle security bulletins (forum posts 482607 and 482608, published 22 September 2026) for full technical details and patches. Defenders running Moodle should prioritize upgrading to the fixed versions (5.0.10, 5.1.7, 5.2.3, or 4.5.14+) and review database query logs for anomalous input patterns consistent with SQLi attempts as an interim mitigation while patching is scheduled.
Given Moodle's prevalence in the education sector, timely patching is recommended to prevent potential data exposure or unauthorized access resulting from SQL injection or security bypass exploitation.

What this brief leaves out
This page is the free tier: the write-up, the severity, the 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.
