What to check
- Applies to
- The 1 CVE named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- A public exploit is recorded for CVE-2026-64638 (templated); no exploitation in the wild is recorded.
ANSSI (CERT-FR) issued an advisory covering multiple vulnerabilities affecting WordPress versions prior to 7.0.3. The flaws could allow an attacker to achieve privilege escalation, breach data confidentiality, perform server-side request forgery (SSRF), conduct indirect remote code injection via cross-site scripting (XSS), and bypass security policies.
One CVE, CVE-2026-64638, is referenced alongside the vendor's own security bulletin. No indication is given in the advisory of active exploitation in the wild; the recommended remediation is to apply the patches released by WordPress in the 7.0.3 update. Given WordPress's widespread deployment across websites of all sectors, unpatched instances remain exposed to these issues until updated.

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 16,433 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.
