Summary
CVE-2026-61131 is a critical authentication bypass vulnerability in Oracle Commerce Platform 11.4.0, published on July 21, 2026 as part of Oracle’s July 2026 Critical Patch Update (CPU). The flaw resides in the Dynamo Application Framework component and allows unauthenticated remote attackers to fully compromise affected installations via HTTP, with no user interaction required. Oracle rates this vulnerability at CVSS 3.1 score 9.8 (Critical), the highest possible severity for a pre-authentication flaw.
Technical details
- Root cause: Missing or improper authentication controls within the Dynamo Application Framework component of Oracle Commerce Platform (CWE-306: Missing Authentication for Critical Function; CWE-287: Improper Authentication; CWE-284: Improper Access Control).
- Trigger conditions: The vulnerability is easily exploitable — an attacker simply requires network access to the target host over HTTP; no account, credentials, or prior foothold are needed.
- Attack vector: Unauthenticated, network-reachable attack over HTTP (AV:N/AC:L/PR:N/UI:N). Low complexity, no user interaction.
- Impact: Successful exploitation results in complete takeover of the Oracle Commerce Platform instance, with full loss of Confidentiality, Integrity, and Availability (C:H/I:H/A:H). This includes the potential for arbitrary command execution, data exfiltration, and persistent access on internet-exposed storefronts.
Affected software
- Oracle Commerce Platform 11.4.0
Severity
- CVSS v3.1 Base Score: 9.8 (Critical)
- Vector String:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate action: Apply the security patch released by Oracle in the July 2026 Critical Patch Update (CPU). Organizations running Oracle Commerce Platform 11.4.0 should consult Oracle’s CPU advisory and apply all relevant patches without delay.
- If patching is not immediately possible: Restrict external network access to Oracle Commerce Platform management interfaces and Dynamo Application Framework endpoints at the network perimeter or WAF layer. Treat any Oracle Commerce instance reachable from the public internet as high risk until patched.
