About this source
CERT-FR is the French government's national cybersecurity incident response team, run by the ANSSI. Their advisory feed publishes vulnerability disclosures, active exploitation warnings, and emergency patching guidance for software in widespread enterprise use: browsers, hypervisors, ERP systems, network equipment, file transfer products. Around 180 advisories a month. The advisories are written in French but cover the same vulnerability universe as CISA, NCSC-UK, BSI's CERT-Bund, and JPCERT, often hours earlier on European-headquartered vendors. Watch this if you patch enterprise software, run a SOC, write detection content, or track Schneider, Dassault, OVH, Atos, or any French-vendor advisory faster than English-language sources will surface it. GovPing publishes each advisory with the affected vendor, severity, and CERT-FR link.
What changed
CERT-FR published a security advisory alerting that a vulnerability discovered in Tenable Nessus products enables arbitrary code execution and poses a risk to data integrity. The affected product versions are Nessus Agent before version 11.1.3 and Nessus before version 10.11.4. The vulnerability is documented under CVE-2026-33694 and references vendor bulletins published by Tenable on 23 April 2026.
Organizations running Tenable Nessus or Nessus Agent should verify their installed versions against the affected version thresholds and apply the available patches referenced in Tenable security bulletins tns-2026-12 and tns-2026-13 as a priority. Failure to remediate could expose systems to remote code execution attacks.
