Oracle GoldenGate EUVD-2026-106392

Exploitation requires network access to the Oracle GoldenGate Admin Server Executable over HTTPS plus a low-privileged authenticated context (CVSS PR:L) - the attacker needs some valid, low-level access to GoldenGate, not a fully unauthenticated position. No user interaction is required (UI:N) and attack complexity is low (AC:L). Limiting factors for defenders: the Admin Server must be network-reachable by the attacker (network segmentation, firewalling, or restricting the Admin Server to trusted management networks materially reduces exposure), and at least low-tier credentials or session access are needed. Affected deployments are GoldenGate 19.1.0.0.0-19.32.0.0, 21.3-21.23, and 23.4-23.26.3.0.0; instances already patched to the October 2026 CPU fix level are not exposed.

This is a genuinely high-priority vulnerability, not a high-CVSS-but-low-real-risk case. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, 8.8) describes a network-reachable, low-complexity flaw requiring only low privileges and no user interaction that yields full takeover (complete confidentiality, integrity, and availability loss) of the GoldenGate instance. The Admin Server is an administrative/management component typically exposed over HTTPS, so a single low-privileged foothold escalates to total product compromise. Mitigating the urgency: no EPSS score, no CISA KEV listing, and no public POC are present in the supplied data, so there is currently no evidence of active or imminent widespread exploitation - exploitation status is 'no public exploit identified at time of analysis.' The signals are therefore consistent rather than conflicting: a severe, easily exploitable flaw with no confirmed exploitation yet. As an Oracle Critical Patch Update item, it should be patched in the next CPU cycle; the window between CPU disclosure and reverse-engineered exploits for Oracle products is historically short, so treat the absence of a POC as a transient state, not as reassurance.

An attacker who holds (or phishes/brute-forces) a low-privileged GoldenGate account, or who reaches the Admin Server from an adjacent network segment, sends crafted HTTPS requests to the Admin Server Executable to abuse the flaw and gain full administrative control of the GoldenGate deployment. No user interaction or victim action is needed, and attack complexity is low. No public exploit code has been identified in the provided data, so this scenario is inferred from the CVSS vector rather than demonstrated.
