Lifecycle Timeline
2DescriptionCVE.org
Vulnerability in the Oracle Retail EFTLink product of Oracle Retail Applications (component: Core/Plugin). Supported versions that are affected are 21.0.0-25.0.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Oracle Retail EFTLink. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Retail EFTLink accessible data as well as unauthorized access to critical data or complete access to all Oracle Retail EFTLink accessible data. CVSS 3.1 Base Score 7.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N).
AnalysisAI
Data compromise in Oracle Retail EFTLink (versions 21.0.0 through 25.0.0) allows a remote unauthenticated attacker with HTTPS network access to read, create, delete, or modify all data accessible to the EFTLink service, despite a high attack-complexity barrier. Disclosed in Oracle's July 2026 Critical Patch Update with a CVSS 3.1 base score of 7.4 (C:H/I:H, no availability impact); no public exploit identified at time of analysis and it is not listed in CISA KEV.
Technical ContextAI
Oracle Retail EFTLink is payment-integration middleware that bridges retail point-of-sale (POS) systems and electronic funds transfer / payment terminals and processors, typically exposed over an HTTPS interface. The affected component is Core/Plugin, per the Oracle advisory. The tag 'Authentication Bypass' aligns with the CVSS PR:N (no privileges required), implying the flaw lets an unauthenticated party reach protected functionality over the network. No CWE was assigned in the input, so the precise root-cause class (e.g., improper authentication or access control) cannot be confirmed from available data; the CPE cpe:2.3:a:oracle_corporation:oracle_retail_eftlink identifies the single affected product line.
RemediationAI
Apply the fixes from the Oracle Critical Patch Update of July 2026 (https://www.oracle.com/security-alerts/cpujul2026.html); a patch is available per the vendor advisory, though a specific fixed version string is not stated in the available data, so consult the CPU patch matrix for the exact patched build for your EFTLink release (21.0.0-25.0.0). Until patched, restrict network reachability of the EFTLink HTTPS endpoint to only trusted POS hosts and payment infrastructure via firewall allowlisting and network segmentation (trade-off: ensure legitimate POS-to-EFTLink and EFTLink-to-processor flows remain permitted), place the service behind a reverse proxy or mTLS-enforcing gateway where feasible, and increase monitoring of EFTLink access logs for anomalous unauthenticated requests. Do not expose the EFTLink interface to untrusted or internet-facing networks.
