Why it matters

CVE-2026-83389 is a medium-severity vulnerability in Oracle HRMS (UK) that allows low-privileged attackers to compromise the system, potentially leading to unauthorized data access. Defenders should prioritize verifying exposure, applying patches, and assessing human interaction risks.

  • Potential unauthorized update, insert, or delete access to Oracle HRMS (UK) accessible data
  • Potential unauthorized read access to a subset of Oracle HRMS (UK) accessible data
  • Requires verification of affected versions and human interaction risks
  • Necessitates applying vendor patches or compensating controls

Technical summary

The vulnerability in Oracle HRMS (UK) affects versions 12.2.3-12.2.15 and allows low-privileged attackers with network access via HTTP to compromise the system, potentially leading to unauthorized data access. The CVSS 3.1 Base Score is 5.4, indicating medium severity with Confidentiality and Integrity impacts. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle HRMS (UK), attacks may significantly impact additional products (scope change).
