How CVE-2026-46925 Works
CVE-2026-46925 is a high-severity vulnerability identified in Oracle Siebel CRM Cloud Applications, specifically within the Siebel Cloud Manager component. The affected versions span from 17.0 through 26.5. The root cause of this vulnerability is categorized as CWE-284: Improper Access Control.
The vulnerability is difficult to exploit, primarily because it requires the attacker to have access to the physical communication segment attached to the hardware where the Siebel CRM Cloud Applications are executing. This means the attack vector is “Adjacent” (AV:A), restricting the attacker to the same local network segment as the target system. The attack complexity is rated as High (AC:H), indicating that successful exploitation requires specific conditions that are beyond the attacker’s control.
Crucially, the vulnerability can be exploited by an unauthenticated attacker (PR:N) without any user interaction (UI:N). This means no credentials are required, and the attack can be carried out without any action from a legitimate user.
The vulnerability has a significant scope change (S:C). While the flaw exists in the Siebel CRM Cloud Applications, a successful attack can impact additional products beyond the initially compromised component, potentially affecting other parts of the Oracle infrastructure.
A successful exploit can lead to a complete takeover of the Siebel CRM Cloud Applications. The CVSS 3.1 Base Score is 8.3, which is rated as HIGH severity. The impact on Confidentiality, Integrity, and Availability is also rated as HIGH (C:H/I:H/A:H), meaning the attacker can gain full access to all sensitive data, modify or corrupt data, and disrupt the availability of the service. The CVSS vector string is CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H.
The vulnerability is not known to be actively exploited in the wild (no CISA KEV listing). It is not automatable, and no public exploit is available. The recommended remediation is to apply the patch from Oracle’s June 2026 Critical Security Patch Update (CSPU).
DailyCVE Form:
Platform: Oracle Siebel CRM

Prediction: August 2026 CSPU
What Undercode Say:
Check Siebel CRM Cloud Applications version SELECT FROM PRODUCT_VERSION WHERE PRODUCT_NAME = 'Siebel CRM Cloud Applications'; Check for the Oracle June 2026 CPU patch Refer to Oracle's advisory: https://www.oracle.com/security-alerts/cspujun2026.html Check network segmentation for Siebel infrastructure Identify systems on the same physical communication segment nmap -sn <target_network>/<subnet>
Analytics:
- CVSS Score: 8.3 (High)
- EPSS Score: 0.27% – 0.3% (Low probability of exploitation)
- Exploitation: None known; not automatable
- Technical Impact: Total
Exploit:
Currently, there is no publicly available exploit for CVE-2026-46925. The vulnerability is considered difficult to exploit due to the requirement for adjacent network access and high attack complexity. While no proof-of-concept (PoC) code has been released, the theoretical attack path would involve:
1. Gaining access to the same physical or logical network segment as the targeted Siebel CRM Cloud Applications server.
2. Crafting a series of malicious network requests to exploit the improper access control within the Siebel Cloud Manager component.
3. Successfully bypassing access controls to execute arbitrary code, leading to a full takeover of the application.
Protection:
- Apply Patches: The primary and most effective protection is to apply the security update provided by Oracle in their June 2026 Critical Security Patch Update (CSPU).
- Network Segmentation: Restrict access to the physical and adjacent communication segments hosting Siebel systems. Ensure that only authorized systems and users can reach the Siebel Cloud Manager infrastructure.
- Inventory and Identification: Identify all instances of Siebel CRM Cloud Applications running versions 17.0 through 26.5 and prioritize them for patching.
- Monitor for Suspicious Activity: Review monitoring logs for unusual activity originating from the local network segment targeting Siebel management infrastructure.
Impact:
- Confidentiality: An attacker can gain complete access to sensitive CRM data, including customer records, sales data, and other proprietary business information (High impact).
- Integrity: The attacker can modify or corrupt critical data within the Siebel CRM system, leading to data integrity issues and potentially impacting business decisions (High impact).
- Availability: The attacker can disrupt the CRM service, causing downtime and impacting business operations that rely on the Siebel platform (High impact).
- Scope Change: The impact is not limited to the Siebel CRM Cloud Applications; it can extend to other connected Oracle products and services, increasing the overall organizational risk.
