AI Analysis

Impact

The vulnerability in Oracle BI Publisher allows an attacker with low privileges that can reach the system over HTTP to gain unauthorized access to sensitive data. It works by bypassing access controls without needing user interaction, resulting in confidentiality compromise while leaving integrity and availability untouched.

Affected Systems

Oracle BI Publisher versions 8.2.0.0.0, 12.2.1.4.0 and 26.01.0.0.0 are affected.

Risk and Exploitability

The CVSS 3.1 Base Score of 6.5 indicates a medium severity issue, with the attack vector being network-based. The EPSS score of <1% indicates a very low but nonzero exploitation probability, and the vulnerability is not listed in CISA KEV, but the ability to compromise data from a low privileged network attacker means organizations should not ignore this flaw. The vulnerability can be exploited simply by accessing the HTTP endpoint, with no need for user interaction or elevated credentials.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the official Oracle patch that addresses CVE-2026-91574 to all affected Oracle BI Publisher installations.
  • Configure network access controls (e.g., firewall or VPN) so that only trusted hosts can reach the Oracle BI Publisher HTTP interface, effectively limiting the attack surface for low privileged users.
  • Enforce stricter authentication and authorization rules within Oracle BI Publisher to ensure that low privileged accounts do not have default access to sensitive data.
  • Enable and review audit logging for the BI Publisher service to detect any attempts to exploit unauthorized data access.
