What to check
- Applies to
- The 3 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
The French national cybersecurity agency (ANSSI) issued an advisory covering multiple vulnerabilities in Drupal core affecting versions prior to 10.6.13, 11.x before 11.3.14, and 11.4.x before 11.4.4. The flaws, tracked as CVE-2026-15916, CVE-2026-15917, and CVE-2026-55805, could allow an attacker to compromise data confidentiality and conduct indirect remote code injection via cross-site scripting (XSS).
Drupal published three corresponding security advisories (SA-CORE-2026-010, -011, -012) on 15 July 2026 detailing the issues and remediation. No indication of active exploitation is provided in the advisory; organizations running affected Drupal versions should apply the vendor's patches as described in the referenced bulletins.

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.
