Summary
CVE-2026-61154 is a critical security vulnerability in the Forge component of Oracle Commerce Guided Search Platform Services version 11.4.0, disclosed as part of Oracle’s July 2026 Critical Patch Update (released July 21, 2026). The flaw allows an unauthenticated attacker with network access via HTTP to fully compromise the affected system, with the potential for complete system takeover. With a CVSS v3.1 base score of 9.8 (Critical), the vulnerability is trivially exploitable — requiring no credentials, no user interaction, and no elevated privileges.
Technical details
- Root cause: Missing or improper authentication controls on critical functions within the Forge component, classified under CWE-306 (Missing Authentication for Critical Function), CWE-287 (Improper Authentication), and CWE-269 (Improper Privilege Management). These weaknesses collectively allow unauthenticated access to protected operations that should require valid credentials.
- Trigger conditions: An unauthenticated attacker with network access to the Forge component over HTTP can trigger the vulnerability directly, with low attack complexity and no prerequisite conditions.
- Attack vector: Network-accessible over HTTP; unauthenticated, no user interaction required.
- Impact: Successful exploitation results in complete compromise of Oracle Commerce Guided Search Platform Services — full loss of confidentiality, integrity, and availability of the affected host.
Affected software
- Oracle Commerce Guided Search Platform Services 11.4.0
Severity
CVSS v3.1 Base Score: 9.8 (Critical)
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: Apply the Oracle July 2026 Critical Patch Update. Oracle has issued patches addressing CVE-2026-61154 for Oracle Commerce Guided Search Platform Services. Refer to the official Oracle CPU advisory for patch download and installation instructions.
- If immediate patching is not possible: Restrict network-level access to the Forge component so it is reachable only from trusted internal networks. Ensure the Oracle Commerce Guided Search Platform Services layer is not directly exposed to untrusted or internet-facing interfaces until the patch is applied.
