Exploitation Conditions

Exploitation requires the attacker to hold a valid low-privileged account on Oracle Business Intelligence Enterprise Edition (PR:L) and to induce a separate user to interact with attacker-supplied content (UI:R) - typically viewing a malicious report, dashboard, or analytics object served by the Analytics Web General component over HTTP. The flaw affects BI EE versions 8.2.0.0.0, 12.2.1.4.0, and 26.01.0.0.0. Key limiting factors: it is not remote-unauthenticated (an account is needed), it cannot fire without victim interaction, and impact is partial (unauthorized read of a subset of data plus limited update/insert/delete, no availability impact), though the scope change means successful attacks may affect additional products beyond BI EE itself.

Impact

This is a moderate-priority issue that should be patched in routine cycles rather than treated as an emergency. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, base 5.4) describes a network-reachable but low-privilege (PR:L) flaw that additionally requires human interaction from a victim other than the attacker (UI:R) and yields only partial confidentiality and integrity impact with no availability impact. The scope change (S:C) plus UI:R strongly indicates a stored/reflected cross-site scripting or similar injection where a low-privileged attacker plants content that executes in another user's authenticated session. No EPSS score, no CISA KEV listing, and no public POC were provided, so there is no public exploit identified at time of analysis and no evidence of active exploitation - the signals are internally consistent in pointing to a meaningful-but-not-critical issue. The 'Authentication Bypass' tag CONFLICTS with the CVSS data: PR:L means the attacker must already be authenticated/low-privileged, and the C:L/I:L/UI:R/S:C profile is characteristic of XSS, not an auth bypass - treat the tag as likely mislabeled and verify against the Oracle CPU note. Overall real-world risk is tempered by the required victim interaction and the attacker's need for some existing access.

Exploit ScenarioDerived

A low-privileged but authenticated Oracle BI EE user crafts a malicious payload (e.g., in a report, dashboard, or analytics object) and lures a higher-privileged user to view it; when that victim opens the content, attacker-controlled script executes in the victim's authenticated context, enabling unauthorized reads and limited data modification that can cross into additional products (scope change). No public exploit code is identified at time of analysis, and the required human interaction raises the bar for reliable exploitation.

AnalysisAIv1 – Oct 20, 2026

Oracle BI EE 8.2.0.0.0, 12.2.1.4.0, and 26.01.0.0.0 contains an HTTP-reachable flaw in the Analytics Web General component that enables a low-privileged authenticated attacker to read a subset of BI-accessible data and perform limited unauthorized updates, inserts, or deletes after inducing another user to interact with crafted content. The scope change raises the possibility of significant impact on additional products, although confidentiality and integrity effects are partial and availability is unaffected. This is a moderate-priority issue for routine patch cycles; no public exploit identified at time of analysis, and no active exploitation is confirmed by the supplied intelligence.

RemediationAI

Apply Oracle's October 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpuoct2026.html) to Oracle BI EE/Analytics; the supplied data does not specify a standalone fixed build number, so use the CPU as the authoritative patch source and verify the fixed version in Oracle's advisory before deployment. Until patched, restrict HTTP access to BI EE to trusted networks or VPN, enforce least privilege and MFA for BI EE accounts, review or approve user-published reports/dashboards, and monitor for anomalous read, update, insert, or delete activity; these controls reduce exposure but trade off self-service accessibility and may slow content publication. Because the vector requires a low-privileged account and victim interaction, removing dormant accounts and limiting who can create or share analytics content lowers the attack surface, though it does not replace patching.

Technical ContextAI · show details

Oracle Business Intelligence Enterprise Edition is a web-based analytics platform whose Analytics Web General component serves reports, dashboards, and related content over HTTP. The authoritative vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) describes a network-reachable flaw that requires a valid low-privileged BI EE account and victim interaction, with partial confidentiality/integrity impact and a scope change that can extend effects to integrated or downstream products. No CWE is supplied, so the precise root-cause class is not confirmed from the available data; the source tag 'Authentication Bypass' should not be read as pre-auth access because PR:L is explicitly required. The combination of PR:L and UI:R points to attacker-supplied content-likely a malicious report, dashboard, or analytics object-that a separate user must view or act on within the BI EE web interface.

DescriptionCVE.org

Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics (component: Analytics Web General). 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 low privileged attacker with network access via HTTP to compromise Oracle Business Intelligence Enterprise Edition. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Business Intelligence Enterprise Edition, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Business Intelligence Enterprise Edition accessible data as well as unauthorized read access to a subset of Oracle Business Intelligence Enterprise Edition accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).
