Defused says threat actors began probing internet-facing Oracle E-Business Suite systems for CVE-2026-101767, a critical unauthenticated SQL injection in the Application Object Library's Thin Client Framework that can chain to remote code execution. Oracle patched the flaw in its October 20, 2026 Critical Patch Update. Affected versions are EBS 12.2.3 through 12.2.15, and the CVSS score is 9.8.
