Lifecycle Timeline
2DescriptionNVD
Vulnerability in the Oracle BI Publisher product of Oracle Analytics (component: BI Platform Security). Supported versions that are affected are 8.2.0.0.0, 12.2.1.4.0 and 26.01.0.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle BI Publisher. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle BI Publisher accessible data as well as unauthorized update, insert or delete access to some of Oracle BI Publisher accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle BI Publisher. CVSS 3.1 Base Score 8.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L).
AnalysisAI
Unauthenticated remote attackers can compromise Oracle BI Publisher 8.2.0.0.0, 12.2.1.4.0 and 26.01.0.0.0 through the HTTP interface, gaining high-impact read access to all data reachable by the application plus limited write and partial denial-of-service capability. Oracle rates the flaw 8.6 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L) and classifies it as easily exploitable in the BI Platform Security component of Oracle Analytics; no public exploit code, EPSS score, or CISA KEV entry was supplied with the source data at time of analysis.

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the Oracle BI Publisher HTTP listener and no credentials, user interaction, or non-default feature enablement per the CVSS vector (AV:N/AC:L/PR:N/UI:N) and Oracle's 'easily exploitable' wording; the flaw lives in the always-present BI Platform Security component, so no optional module must be switched on. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 8.6 with AV:N/AC:L/PR:N/UI:N describes an unauthenticated, low-complexity, network-reachable attack requiring no user interaction, and Oracle's own advisory language ('easily exploitable') corroborates that this is not a theoretical edge case - the SSVC-style read is exploitation: none known, automatable: yes, technical impact: partial (high confidentiality, limited integrity/availability). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Oracle fix published in the security advisory referenced by this CVE (https://www.oracle.com/security-alerts/cspusep2026.html, Oracle Critical Security Patch Update cspusep2026); because the advisory names affected versions 8.2.0.0.0, 12.2.1.4.0 and 26.01.0.0.0 but the supplied data does not include the exact patched build numbers, verify the specific patch or bundle identifier on Oracle Support (My Oracle Support) before scheduling maintenance. … Detailed patch versions, workarounds, and compensating controls in full report. |
