MITRE ATT&CK
1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires the attacker to already have local logon access (a valid low-privileged account, PR:L) to the infrastructure where Oracle GoldenGate executes; per AV:L this cannot be triggered remotely over the network and needs no user interaction (UI:N) and low attack complexity (AC:L). The affected deployment must be running Oracle GoldenGate 23.4 through 23.26.1 with the Libraries component in use. Limiting factors: the local-only vector rules out unauthenticated internet exploitation, and the requirement for a pre-existing authenticated foothold on the GoldenGate host is the primary constraint reducing real-world exposure to environments where an attacker has already achieved local access. |
| Impact | The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, base 7.8) describes a locally exploitable, low-complexity issue requiring only low privileges and no user interaction, yielding full compromise of GoldenGate - a serious outcome but gated behind the need for an existing foothold on the host. There is no EPSS score, SSVC decision, KEV listing, or public POC in the provided data, so the practical exploitation likelihood signals are absent rather than reassuringly low; the local attack vector meaningfully constrains mass exploitation, making this a privilege-escalation/lateral-movement risk on already-accessed systems rather than an internet-facing emergency. Note a mild tension: Oracle's 'Information Disclosure' tag implies confidentiality focus, yet the vector asserts equal integrity and availability impact - treat the full-takeover framing from the vector as authoritative and verify scope with Oracle if disclosure-only behavior is expected. |
| Exploit ScenarioDerived | An attacker who already holds a low-privileged local account on the server running Oracle GoldenGate - for example a compromised operator login or a limited service account - invokes the vulnerable Libraries code path to gain full control of the GoldenGate instance and its replicated data flows. No user interaction or network exposure is needed, but the attacker must first have logon access to the host. No public POC has been identified at time of analysis. |

Alert meAnalysisAIv1 – Jul 22, 2026
Local privilege-based takeover in Oracle GoldenGate 23.4 through 23.26.1 (Libraries component) allows a low-privileged attacker with logon access to the host running GoldenGate to fully compromise the product, with high confidentiality, integrity, and availability impact. Disclosed in Oracle's July 2026 Critical Patch Update (CVSS 3.1 base 7.8), it requires local authenticated access rather than network exploitation. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
RemediationAI
Apply the fixes delivered in Oracle's July 2026 Critical Patch Update (Patch available per vendor advisory; consult https://www.oracle.com/security-alerts/cpujul2026.html for the exact patched build for your GoldenGate 23.x deployment, as no single fixed version string was included in the source data). Because exploitation requires local logon to the host, the most effective compensating controls until patching are to tighten OS-level access: restrict interactive and service-account logon on GoldenGate servers to a minimal set of trusted administrators, enforce least privilege so low-privileged local accounts cannot run or influence GoldenGate processes, and audit filesystem permissions on GoldenGate library and installation directories to prevent tampering by non-admin users - the trade-off is added operational friction for legitimate operators. Monitor GoldenGate process and host logs for anomalous local activity as a detective control while the patch is scheduled.

Technical ContextAI · show details
Oracle GoldenGate is a real-time data replication and integration platform used to capture, route, and apply transactional changes across heterogeneous databases for high availability, migration, and streaming pipelines. The flaw resides in the Libraries subcomponent - the shared native/runtime libraries loaded by GoldenGate processes - which suggests a code-level defect (for example unsafe library loading, memory handling, or trust in a locally controllable input) that a local user can leverage to escalate control over the GoldenGate runtime. No CWE was assigned by Oracle or NVD, so the precise root-cause class cannot be confirmed; the Oracle tag 'Information Disclosure' points toward a confidentiality-affecting weakness, though the CVSS vector shows full high impact across all three dimensions, indicating complete takeover rather than mere disclosure.

DescriptionCVE.org
Vulnerability in Oracle GoldenGate (component: Libraries). Supported versions that are affected are 23.4-23.26.1. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle GoldenGate executes to compromise Oracle GoldenGate. Successful attacks of this vulnerability can result in takeover of Oracle GoldenGate. CVSS 3.1 Base Score 7.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
Executive ViewAI
Oracle GoldenGate 23.4 through 23.26.1 is vulnerable to privilege escalation by authorized system users, enabling complete takeover of critical database replication infrastructure. This threatens the integrity and availability of data synchronization operations that many organizations depend on for compliance and operational continuity.
Restrict local logon access to GoldenGate systems to privileged administrators only; implement host-based privilege escalation detection and alerting; enforce strict access controls and privileged account management; isolate GoldenGate infrastructure from untrusted networks; enable comprehensive audit logging of all local system access and elevation attempts; monitor for suspicious activity patterns consistent with privilege escalation.
