CVE-2026-34273
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVulnerability in Oracle GoldenGate (component: Libraries). Supported versions that are affected are 23.4-23.10. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle GoldenGate. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle GoldenGate accessible data. CVSS 3.1 Base Score 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceInformation disclosure vulnerability in Oracle GoldenGate's Libraries component. Unauthenticated remote attackers with network access via HTTP can read a subset of accessible data. This is a confidentiality-only impact with no modification or disruption of system availability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Oracle GoldenGate installationLocate GoldenGate installation directories (typically $OGG_HOME) and check for oggcore.jar or related library files. On Linux/Unix, run: find / -name 'oggcore.jar' 2>/dev/null or check common install paths like /opt/oracle/ogg, /u01/ogg, or Oracle Middleware home directories.Affected if GoldenGate software is present on the system
-
Determine installed GoldenGate versionRun the GoldenGate version command: ./ggsci -version or check the OGG_VERSION file in the installation directory. Alternatively, look at version information in the README or patch inventory files.Affected if Installed version is >= 23.4 and <= 23.10
-
Check if HTTP port is enabledExamine GoldenGate configuration files (parameter files, mgr.prm) for HTTP port definitions. Run: grep -r 'HTTP_PORT' or 'PORT' in the $OGG_HOME/dirprm directory. Also check if the Management Server (MS) or Admin Server HTTP interface is configured.Affected if HTTP-based network listener is configured and active on any port
-
Verify network exposure of GoldenGate endpointsReview firewall rules and network ACLs to determine if GoldenGate HTTP ports (commonly 8080, 8443, or configured custom ports) are accessible from untrusted networks. Run: netstat -tlnp | grep -E 'ogg|mgr|admin' or check listener status via GGSCI command: INFO MGR.Affected if GoldenGate HTTP endpoints are reachable from outside the trusted network or internet
The environment is affected if Oracle GoldenGate version 23.4 through 23.10 is installed with HTTP network access enabled and exposed to network attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply Oracle patches for Oracle GoldenGate versions 23.4-23.10 when released. Until patches are available, restrict network access to GoldenGate endpoints and monitor for unauthorized access attempts.
