> CERT-FR advisory lists multiple Oracle WebLogic Server and Proxy Plug-in vulnerabilities enabling remote DoS, data integrity and confidentiality breaches; patch via Oracle's October 2026 CPU.

CERT-FR published an advisory summarizing multiple vulnerabilities affecting Oracle WebLogic Server (versions 12.2.1.4.0, 14.1.2.0.0, and 15.1.1.0.0) and Oracle WebLogic Server Proxy Plug-in (versions 12.2.1.4.0 and 14.1.2.0.0). The flaws collectively allow a remote attacker to cause denial of service, compromise data confidentiality, and undermine data integrity. This advisory references Oracle's Critical Patch Update (CPU) for October 2026 (cpuoct2026), which consolidates patches across Oracle's product lines.

The bulletin lists a large number of CVE identifiers associated with these WebLogic vulnerabilities, though no technical details, exploitation status, or proof-of-concept availability are provided in this notice. No in-the-wild exploitation is mentioned. Defenders running affected WebLogic Server or Proxy Plug-in versions should consult Oracle's official security bulletin for the complete technical details, CVSS scores, and patches, and prioritize patching per their internal risk assessment given WebLogic's history as a frequent target for exploitation in enterprise environments.

As this is a CERT advisory aggregating a vendor's periodic patch bulletin with no indication of active exploitation, it should be treated as routine patch management guidance rather than an urgent incident response matter, though organizations should not delay remediation given WebLogic's exposure profile.
