What to check
- Applies to
- The 6 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.
CERT-FR has issued an advisory covering multiple vulnerabilities affecting Oracle Database Server versions 19.3 through 19.32, 21.3 through 21.23, and 23.4.0 through 23.26.3. The flaws stem from Oracle's August 2026 Critical Patch Update (cspuaug2026) and collectively allow an attacker to achieve remote code execution, remote denial of service, and unauthorized access to or disclosure of sensitive data, as well as impacts on data integrity.
Six CVEs are referenced in the bulletin without further technical detail provided in this advisory. No public exploitation, proof-of-concept, or threat actor activity is mentioned. Organizations running affected Oracle Database Server versions should consult Oracle's official security alert for patch details and apply updates according to their standard change-management procedures.

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 16,566 reports from 147 sources, 722 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.
