CVE-2026-46819: Oracle Internet Procurement Connector Unauthenticated Remote Code Execution

CVE-2026-46819 is a critical vulnerability within the Internal Operations component of Oracle Internet Procurement Connector, a part of Oracle E-Business Suite. The vulnerability affects supported versions 12.2.3 through 12.2.15. This easily exploitable flaw allows an unauthenticated attacker with network access via HTTP to compromise the Oracle Internet Procurement Connector. Successful exploitation can lead to unauthorized creation, deletion, or modification of critical data, as well as unauthorized access to sensitive information. This poses a significant risk to organizations using the affected versions of Oracle E-Business Suite.

Attack Chain

1. The attacker identifies a vulnerable Oracle Internet Procurement Connector instance accessible via HTTP.
2. The attacker sends a specially crafted HTTP request to the vulnerable Internal Operations component.
3. The crafted request exploits the lack of authentication and authorization checks.
4. The vulnerability allows the attacker to bypass security controls.
5. The attacker gains unauthorized access to the Oracle Internet Procurement Connector’s data.
6. The attacker creates, modifies, or deletes critical data within the system.
7. The attacker exfiltrates sensitive data from the Oracle Internet Procurement Connector.
8. The attacker achieves complete compromise of the Oracle Internet Procurement Connector, potentially impacting other connected systems.

Impact

Successful exploitation of CVE-2026-46819 can result in unauthorized creation, deletion, or modification of critical data, as well as unauthorized access to sensitive information. The vulnerability has a CVSS 3.1 base score of 9.1, indicating a critical impact on confidentiality and integrity. This could lead to significant financial losses, reputational damage, and regulatory fines for affected organizations. The lack of authentication required for exploitation makes this vulnerability particularly dangerous.
