Exploitation Conditions

No special configuration is required beyond a default network-accessible Oracle GoldenGate deployment - the CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms unauthenticated exploitation with low complexity and no user interaction over HTTP. The vulnerability is bounded to GoldenGate versions 23.4 through 23.10; systems running versions outside this range are not listed as vulnerable. Exploitation is further limited by the partial confidentiality scope - only a subset of GoldenGate-accessible data is exposed, and integrity and availability remain intact. Organizations that have restricted HTTP access to GoldenGate behind internal network segments or firewall rules to trusted hosts have meaningfully reduced real-world exposure even without patching, since the attacker must have network-layer reachability to the HTTP interface to exploit the flaw.

Impact

The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) paints a straightforward picture: easily reachable over the network, no authentication required, no complexity barrier. These metrics alone would suggest medium urgency. However, the broader intelligence picture significantly moderates that assessment. EPSS sits at just 0.03% (8th percentile), one of the lowest exploitation probability bins, indicating the security research and threat actor community has shown minimal interest in weaponizing this flaw. CISA KEV does not list this CVE, and SSVC independently corroborates exploitation status as none. The technical impact is rated partial, and the confidentiality loss is bounded - only a subset of GoldenGate-accessible data is exposed, not full system access. The automatable=yes SSVC flag is the one signal worth noting, as it means a scanner or script could probe large numbers of GoldenGate instances systematically; however, without evidence of active campaigns, this is a theoretical risk. The overall picture is a low-priority patching item - real but not urgent absent threat intelligence changes.

Exploit ScenarioDerived

An unauthenticated attacker with network access to a GoldenGate 23.4-23.10 HTTP endpoint sends a crafted HTTP request that triggers the CWE-200 disclosure in the Libraries component, receiving a subset of GoldenGate-accessible data - potentially including replication metadata, configuration details, or other internally scoped information depending on the deployment context. No public exploit code has been identified at time of analysis, and the low EPSS score suggests this scenario remains largely theoretical rather than actively pursued by threat actors.

AnalysisAIv1 – Jul 24, 2026

Unauthenticated information disclosure in Oracle GoldenGate versions 23.4 through 23.10 exposes a subset of accessible data to remote attackers via HTTP, requiring no credentials or user interaction. The Libraries component contains a CWE-200 flaw that allows network-based attackers to read protected data, though impact is limited to partial confidentiality - integrity and availability are unaffected. No active exploitation has been identified (not in CISA KEV), and EPSS places exploitation probability at 0.03%, consistent with the SSVC exploitation status of none despite the automatable flag.

RemediationAI

Apply Oracle's Critical Patch Update for April 2026, documented at https://www.oracle.com/security-alerts/cpuapr2026.html, which addresses this vulnerability in the GoldenGate Libraries component. An exact patched build version is not independently confirmed from available data - consult the Oracle CPU directly to identify the specific fixed release for your deployment. If immediate patching is not operationally feasible, restrict inbound HTTP access to the GoldenGate service to only trusted internal IP ranges using host-based firewall rules or network ACLs, since the attack vector is AV:N over HTTP; this does not eliminate the flaw but substantially limits the exposure surface. Note that many GoldenGate deployments reside in segmented internal networks, which may already partially mitigate network reachability without additional controls.

Technical ContextAI · show details

Oracle GoldenGate is Oracle's enterprise real-time data integration and replication platform, used predominantly in heterogeneous database environments across financial services, telecommunications, and large enterprise data centers. The affected component is the Libraries subsystem within GoldenGate, accessible over HTTP. The root cause is CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor), meaning the software returns data to callers who have not been authenticated or authorized to receive it - a classic information leakage pattern typically manifesting as improperly gated API responses or error messages. The CPE string (cpe:2.3:a:oracle_corporation:oracle_goldengate:*:*:*:*:*:*:*:*) covers the full affected version range of 23.4 through 23.10 as defined by Oracle's April 2026 CPU.
