Unauthenticated read and write access to production data
Published Sep 15, 2026 · Updated Sep 15, 2026
Improper access control in Oracle Work in Process 12.2.3 through 12.2.15 allows remote attackers to read and alter production data via TCP. Oracle identifies the Workbenches component but does not disclose the vulnerable code path or the operation performed incorrectly on TCP input. Exploitation is unauthenticated but requires access to the physical communication segment; it can expose, create, delete, or modify all accessible Work in Process data.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=12.2.3 <=12.2.15
