Severity by source
AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Network-reachable over T3/IIOP with low complexity and no interaction; PR:L reflects the required low-privileged foothold, and scope change plus full takeover justify S:C and C/I/A:H.

Lifecycle Timeline
2DescriptionCVE.org
Vulnerability in the Oracle WebCenter Enterprise Capture product of Oracle Fusion Middleware (component: Client Bundle). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via T3, IIOP to compromise Oracle WebCenter Enterprise Capture. While the vulnerability is in Oracle WebCenter Enterprise Capture, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle WebCenter Enterprise Capture. CVSS 3.1 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
AnalysisAI
Privilege escalation to full takeover in Oracle WebCenter Enterprise Capture 12.2.1.4.0 and 14.1.2.0.0 (Client Bundle component) allows a low-privileged attacker with network access over the WebLogic T3/IIOP protocols to fully compromise the product, with scope change meaning impact extends to other products in the environment. Rated CVSS 9.9 with high confidentiality, integrity, and availability impact. Disclosed in Oracle's July 2026 Critical Patch Update; no public exploit identified at time of analysis and not listed in CISA KEV.
Technical ContextAI
Oracle WebCenter Enterprise Capture is a document imaging/capture application built on the Oracle Fusion Middleware / WebLogic Server stack. The affected surface is the Client Bundle component, and the attack is delivered over T3 and IIOP - proprietary RMI-style remote invocation protocols exposed by WebLogic Server. These protocols have historically been vectors for deserialization and remote object abuse in the Fusion Middleware ecosystem. No CWE was assigned in the source data, so the precise root-cause class (e.g., insecure deserialization, authorization bypass) cannot be confirmed from the provided intelligence; the scope-change flag (S:C) indicates the vulnerable component can affect resources beyond its own security authority, consistent with a shared WebLogic runtime where a compromise of Capture can pivot into co-hosted middleware services.
RemediationAI
Apply the fixes delivered in the Oracle Critical Patch Update of July 2026 (https://www.oracle.com/security-alerts/cpujul2026.html); the input does not name an exact patched build number, so Patch available per vendor advisory - administrators should map their WebCenter Enterprise Capture 12.2.1.4.0 and 14.1.2.0.0 deployments to the corresponding CPU patch set from that advisory. Because exploitation rides the WebLogic T3 and IIOP protocols, the strongest compensating control until patching completes is to restrict or disable those protocols: configure WebLogic connection filters (weblogic.security.net.ConnectionFilterImpl) to allow T3/T3S/IIOP only from trusted management hosts, and block external access to the WebLogic listen ports at the network firewall - note this can break legitimate RMI clients, cluster replication, and remote JMX/administration that rely on T3/IIOP, so validate in a staging environment first. Additionally enforce least privilege on Capture accounts to reduce the pool of low-privileged identities that satisfy the PR:L precondition.
