What to check
- Applies to
- The 13 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 published an advisory detailing multiple vulnerabilities discovered in Oracle WebLogic Server affecting versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0. The vulnerabilities enable attackers to execute arbitrary code remotely, cause denial of service conditions, and compromise data confidentiality and integrity.
Oracle addressed these issues in their June 2026 Critical Patch Update, releasing fixes for 13 CVEs. The affected WebLogic Server versions are widely deployed in enterprise environments for Java application hosting and middleware services. Organizations running these versions should prioritize patching to mitigate the risk of exploitation.
The advisory references Oracle's security bulletin for detailed remediation guidance. No active exploitation or proof-of-concept code is mentioned in the CERT-FR notice, though the severity of remote code execution capabilities warrants prompt attention from affected organizations.

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.
