MITRE ATT&CK
2 techniques across 2 tactics: Collection, Discovery The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | The attacker must possess a valid low-privileged user account on the Oracle BI Publisher instance with HTTP network access to the server - exploitation is not possible without credentials. The XML Services component must be active and network-reachable; this component is part of BI Publisher's core functionality and is enabled by default in supported deployments. The CVSS vector AV:N/AC:L/PR:L/UI:N confirms exploitation requires no special configuration, no user interaction, and no elevated privileges beyond basic authentication. Exploitation is limited to the BI Publisher data boundary (S:U - unchanged scope) and does not extend to underlying OS or adjacent Oracle platform components. Organizations that restrict BI Publisher access exclusively to fully trusted internal users, or that place the application behind strict network perimeter controls, face substantially reduced real-world risk. |
| Impact | The CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N presents a realistic and exploitable threat profile: network-accessible, low attack complexity, requiring only a valid low-privileged account, with no user interaction needed. The high confidentiality impact (C:H) indicates the attacker can access all BI Publisher data rather than a partial subset. The 'Authentication Bypass' tag elevates concern: while PR:L confirms some credential is required, the bypass characteristic implies that credential grants access far beyond its intended authorization scope, enabling any user to act as a de facto administrator within the XML Services data layer. No EPSS data was provided, precluding probabilistic exploitation likelihood assessment. The absence of a CISA KEV listing and no identified POC reduces immediate urgency, but the low complexity and low privilege bar mean any insider threat or account-compromise scenario could leverage this without specialized tooling. Organizations exposing BI Publisher to semi-trusted user pools (contractors, partners, broad internal users) face materially higher risk than those with tightly controlled access. |
| Exploit ScenarioDerived | An attacker holding any valid low-privileged Oracle BI Publisher account - such as a read-only report viewer or a compromised service account - sends a crafted HTTP request to the XML Services component, exploiting the authorization bypass to retrieve data beyond their permitted scope. By manipulating XML service request parameters or endpoint paths, the attacker extracts sensitive report data, embedded credentials, or business-critical datasets accessible to the BI Publisher instance. No public POC has been identified, but the low attack complexity and absence of required user interaction mean this is achievable by any authenticated attacker with basic HTTP tooling. |

Alert meAnalysisAIv1 – Jul 22, 2026
Unauthorized data disclosure in Oracle BI Publisher's XML Services component allows any low-privileged, network-authenticated attacker to access all data within the application via HTTP. Affected across three major release lines - 8.2.0.0.0, 12.2.1.4.0, and 26.01.0.0.0 - the flaw carries a CVSS 3.1 score of 6.5 with high confidentiality impact and no integrity or availability dimension. The 'Authentication Bypass' tag suggests the vulnerability enables privilege escalation within the product's authorization model rather than a full pre-auth bypass; no public exploit or CISA KEV listing has been identified at time of analysis.
RemediationAI
Apply Oracle's July 2026 Critical Patch Update patches for all affected BI Publisher release lines (8.2.0.0.0, 12.2.1.4.0, and 26.01.0.0.0) via the official advisory at https://www.oracle.com/security-alerts/cpujul2026.html. Exact patched version identifiers are not independently confirmed in the available data - consult the Oracle CPU advisory directly for the specific patch bundle or version increment applicable to each release. As a compensating control pending patching, restrict network-level access to the XML Services endpoint using firewall rules or a reverse proxy access control list to limit exposure to the minimum required user set. If XML Services functionality is not operationally required, consider disabling or blocking the component entirely, noting that this will impact XML-based report data sourcing and delivery. Additionally, audit BI Publisher user accounts to identify and revoke any unnecessary low-privileged accounts, thereby reducing the pool of potential exploitation vectors. No workaround is confirmed by the vendor advisory beyond applying the CPU patch.

Technical ContextAI · show details
Oracle BI Publisher is Oracle's enterprise-grade report creation and publishing platform, delivered as part of the Oracle Analytics suite. The affected component is XML Services, which handles XML-based data sources, report definitions, and delivery pipelines - a core subsystem for data retrieval and transformation. The 'Authentication Bypass' tag in the advisory metadata, combined with the CVSS impact profile (C:H/I:N/A:N, PR:L), points to an authorization control deficiency within the XML Services layer, likely analogous to CWE-284 (Improper Access Control) or CWE-863 (Incorrect Authorization) - though Oracle has not specified a CWE for this entry. The vulnerability is disclosed as part of Oracle's Critical Patch Update (CPU) for July 2026 (advisory: https://www.oracle.com/security-alerts/cpujul2026.html), corroborated by EUVD-2026-47031. The scope being unchanged (S:U) confirms the data exposure is bounded within BI Publisher itself rather than cascading to adjacent Oracle platform components.
