Oracle Database Server patches dozens of CVEs
Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.
CERT-FR advisory covers multiple Oracle Database Server vulnerabilities enabling remote code execution, denial of service, and data exposure; patches available.
CERT-FR has published an advisory detailing numerous vulnerabilities affecting Oracle Database Server and related components, including Oracle Net Services, Oracle OLAP, and Oracle SQLcl, across versions 19.3-19.32, 21.3-21.23, and 23.4.0-23.26.3. The vulnerabilities stem from Oracle's October 2026 Critical Patch Update (CPU) bulletin and collectively allow attackers to achieve remote code execution, remote denial of service, data confidentiality breaches, data integrity compromise, and security policy bypass.
No in-the-wild exploitation is mentioned in this advisory. Defenders running affected Oracle Database Server versions should consult Oracle's official CPU bulletin (cpuoct2026) for patch details and apply fixes according to their organization's patch management policy, prioritizing systems exposed to untrusted networks given the breadth of impact categories including remote code execution.

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 13,960 reports from 143 sources, 519 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 — about forty a week that are yours, not the four hundred that are not.
