What to check
- Applies to
- The 5 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 summarizing multiple vulnerabilities affecting Oracle WebLogic Server versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0. The vulnerabilities, tracked under five CVE identifiers, allow an attacker to achieve remote arbitrary code execution. No further technical detail on exploitation vectors, exploitability without authentication, or in-the-wild exploitation is provided in this advisory.
Oracle addressed these issues as part of its Critical Patch Update cspusep2026, released 15 September 2026. Defenders running any of the affected WebLogic versions should consult the Oracle security bulletin and apply the corresponding patches. As WebLogic is a common target for opportunistic and targeted attackers seeking initial access into enterprise environments, organizations should prioritize patching internet-facing or otherwise exposed WebLogic instances and monitor for post-patch exploitation attempts.

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.
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.
