| Exploitation Conditions | No special conditions are required beyond network-level HTTP access to an Oracle E-Business Suite instance running a Purchasing component version between 12.2.3 and 12.2.15. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms unauthenticated remote exploitation against default configurations of Oracle Purchasing - no specific feature flag, non-default setting, or prior authentication is required. Exploitation is constrained to confidentiality impact only (C:H/I:N/A:N); the attacker cannot modify data or cause denial of service through this vulnerability. The version scope (12.2.3-12.2.15) limits exposure to organizations that have not yet applied the August 2026 CPU. Organizations with Oracle EBS HTTP access restricted to trusted internal networks via firewall or network segmentation have meaningfully reduced but not eliminated risk. |
| Impact | The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) presents a high-priority signal: fully remote, unauthenticated, low-complexity exploitation with no user interaction required. The authentication bypass tag reinforces that this is a structural access control failure rather than a narrow edge-case requiring unusual configuration. Confidentiality impact is high - Oracle Purchasing data can include vendor pricing, contractual terms, procurement strategies, and financial commitments, making this a meaningful business espionage risk. EPSS data was not provided in the input, limiting probabilistic exploitation forecasting. The vulnerability is not currently listed in CISA KEV, and no public POC has been identified, which moderates the urgency slightly compared to confirmed in-the-wild exploitation. However, the combination of zero prerequisites and network accessibility means this could be trivially automated against exposed EBS instances by any attacker who identifies the target. Organizations with Oracle EBS Purchasing exposed to untrusted networks should treat this as a priority patch. |
| Exploit ScenarioDerived | An attacker with network-level HTTP access to an Oracle E-Business Suite instance sends crafted HTTP requests to the Oracle Purchasing component, bypassing authentication controls due to the structural flaw. Without supplying any credentials, the attacker retrieves sensitive procurement records - purchase orders, vendor pricing, approval histories - potentially enabling competitive intelligence gathering or fraud enablement. No public POC has been identified, but the low attack complexity (AC:L) and zero authentication requirement suggest exploitation is structurally straightforward for an attacker who has identified the endpoint. |

Alert meAnalysisAIv1 – Aug 19, 2026
Unauthenticated HTTP access to Oracle Purchasing (a component of Oracle E-Business Suite versions 12.2.3-12.2.15) enables remote attackers to read critical or complete procurement data with no credentials, user interaction, or elevated attack complexity. Tagged as an authentication bypass by EUVD (EUVD-2026-61894) and disclosed through Oracle's August 2026 Critical Patch Update, the flaw carries a CVSS 3.1 base score of 7.5, reflecting a fully network-exposed, zero-prerequisite attack path. No public exploit code or active CISA KEV listing has been identified at time of analysis.
RemediationAI
Apply Oracle's August 2026 Critical Patch Update (CPU), which addresses this vulnerability in the Oracle Purchasing component of E-Business Suite. The advisory and patch instructions are available at https://www.oracle.com/security-alerts/cspuaug2026.html. An exact patched version number beyond the affected range was not independently confirmed from the available data - consult the CPU directly for the specific patch identifier. If immediate patching is not feasible, implement network-layer controls to restrict HTTP access to the Oracle EBS instance to trusted internal IP ranges only, using firewall rules or network segmentation; this reduces the attack surface for this unauthenticated network vector but does not remediate the underlying flaw and may impact legitimate remote access. Additionally, enable and review Oracle EBS HTTP access logs for anomalous unauthenticated requests targeting Purchasing endpoints as a detection measure.

Technical ContextAI · show details
Oracle E-Business Suite (EBS) is Oracle's flagship integrated ERP platform, and the Purchasing module manages procurement workflows including purchase orders, vendor management, and approval chains - all highly sensitive business data. The vulnerability manifests in the HTTP-accessible layer of the Purchasing component, where an authentication bypass flaw (per EUVD tags) allows requests to proceed without valid session credentials. No CWE was formally assigned in the NVD record, but the behavior is consistent with CWE-284 (Improper Access Control) or CWE-306 (Missing Authentication for Critical Function). Affected CPE spans Oracle EBS versions 12.2.3 through 12.2.15. The attack surface is the standard Oracle EBS HTTP stack, which is typically internet- or intranet-accessible in enterprise deployments.

DescriptionCVE.org
Vulnerability in the Oracle Purchasing product of Oracle E-Business Suite (component: Other issue). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Purchasing. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Purchasing accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
Executive ViewAI
Oracle E-Business Suite Purchasing module (versions 12.2.3-12.2.15) is vulnerable to unauthenticated remote access to complete procurement data, exposing organizations to potential data breaches affecting supplier contracts, pricing, and purchase orders. The vulnerability impacts any organization running these specific E-Business Suite versions, particularly those with internet-facing systems or cloud deployments. With no vendor patch currently available, immediate network-level compensating controls are critical to prevent competitive damage and regulatory exposure.
Implement network-level isolation of affected systems; enforce firewall and WAF rules blocking HTTP access to the Purchasing module; require VPN or segmented network connectivity for all users; disable HTTP endpoints where feasible and mandate HTTPS-only communication; enable comprehensive access logging with automated alerting for suspicious Purchasing data access; apply rate limiting to reduce attack surface; consider additional authentication overlays via Oracle middleware if available; maintain continuous monitoring of Oracle advisories for patch availability.
