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.
ANSSI (CERT-FR) issued an advisory covering multiple vulnerabilities in Roundcube Webmail affecting versions 1.5.x prior to 1.5.14, 1.6.x prior to 1.6.14, and 1.7.x prior to 1.7-rc5. The flaws allow an attacker to compromise data confidentiality, bypass security policies, perform server-side request forgery (SSRF), inject remote code indirectly via cross-site scripting (XSS), and conduct cross-site request forgery (CSRF) attacks.
Three CVEs are referenced (CVE-2026-35537, CVE-2026-35544, CVE-2026-35545). Roundcube published corresponding security updates on 18 March 2026. No evidence of active exploitation is mentioned in the advisory; administrators are advised to apply the vendor patches referenced in the bulletin.

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.
