{"id":"CVE-2026-83394","kind":"vulnerability","aliases":["CVE-2026-83394"],"related":[],"title":"Oracle Demand Planning: low-privilege HTTP attack exposes critical data","description":"Vulnerability in the Oracle Demand Planning product of Oracle Supply Chain (component: Internal Operations).  Supported versions that are affected are 12.1 and  12.2. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Demand Planning.  Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Demand Planning, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in  unauthorized access to critical data or complete access to all Oracle Demand Planning accessible data. CVSS 3.1 Base Score 6.8 (Confidentiality impacts).  CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:N/A:N).","summary":"Oracle Demand Planning versions 12.1 and 12.2 contain a flaw in the Internal Operations component that lets a low-privileged user with network access over HTTP reach data beyond their rights. A successful attack needs a second person to interact with it and can expose critical data across the product.","severity":"medium","cvss":6.8,"epss":null,"exploited":false,"exploited_at":null,"products":[],"ecosystems":[],"tags":["enterprise","oracle","oracle-demand-planning","supply-chain","vendor"],"not_affected_if":["other-versions"],"how_to_check":"- Check the installed Oracle Demand Planning version against the affected releases 12.1 and 12.2\n- Review the Oracle Critical Patch Update advisory for CVE-2026-83394 to confirm the patched build","fix":"- Apply the Oracle security patch for Oracle Demand Planning 12.1 and 12.2 from the Oracle Critical Patch Update\n- Unknown: the exact patched version numbers are not in the sources","status":"open","published_at":"2026-10-20T22:19:55+00:00","first_seen_at":"2026-10-23T21:57:25+00:00","triaged_at":"2026-10-25T03:43:11+00:00","updated_at":"2026-10-25T03:43:11+00:00","category":"vendor","confidence":0.6,"triage":{"at":"2026-10-25T03:43:11Z","model":"claude-haiku-5-5","output":{"fix":"- Apply the Oracle security patch for Oracle Demand Planning 12.1 and 12.2 from the Oracle Critical Patch Update\n- Unknown: the exact patched version numbers are not in the sources","reach":"network","title":"Oracle Demand Planning: low-privilege HTTP attack exposes critical data","impact":"medium","summary":"Oracle Demand Planning versions 12.1 and 12.2 contain a flaw in the Internal Operations component that lets a low-privileged user with network access over HTTP reach data beyond their rights.
