What to check
- Applies to
- The 2 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/CERT-FR) issued an advisory covering multiple vulnerabilities in Roundcube Webmail, an open-source webmail client widely deployed by organizations to provide browser-based email access. The flaws affect Roundcube versions 1.6.x prior to 1.6.17 and 1.7.x prior to 1.7.2, and include a server-side request forgery (SSRF) vulnerability, a remote indirect code injection (stored/reflected XSS), a remote denial-of-service condition, and a security policy bypass.
The vendor released fixed versions (1.6.17 and 1.7.2) on July 5, 2026, addressed under CVE-2026-54432 and CVE-2026-54433. No evidence of active exploitation is mentioned in the advisory; this is a standard vendor patch notification. Organizations running affected Roundcube deployments should apply the updates promptly, as webmail interfaces are a common target for phishing-driven credential theft and lateral movement when left unpatched.

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.
