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.
ANSSI (CERT-FR) published an advisory covering multiple vulnerabilities in Veeam products, specifically Veeam Backup & Replication versions 13.x prior to 13.0.3 and Veeam ONE versions 13.x prior to 13.0.2 Patch 1. The flaws, tracked as CVE-2026-58070 and CVE-2026-65641, could allow an attacker to compromise data confidentiality and bypass security policy controls. No indication of active exploitation is provided in the advisory.
Veeam has released security bulletins (kb4902 and kb4905, dated 25 August 2026) with patches addressing these issues. Organizations running affected versions of Veeam Backup & Replication or Veeam ONE should apply the vendor-supplied updates promptly, given that backup infrastructure is a high-value target for attackers seeking to exfiltrate sensitive data or disable recovery capabilities.

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.
