CVE-2026-60704 is an improper authorization vulnerability affecting the Siebel Cloud Manager component within Oracle Siebel CRM Cloud Applications. The flaw resides in the authorization logic that governs access to critical cloud management functions and underlying customer data. An unauthenticated remote attacker can exploit this weakness by sending specially crafted HTTP requests to the Siebel Cloud Manager endpoint, bypassing authentication checks entirely. Because the vulnerability requires no user interaction and no privileges, it is trivially exploitable over the network.
The root cause is a missing or insufficient authorization check (CWE-285) in an unknown function of the Siebel Cloud Manager. When processing certain API calls, the component fails to verify whether the requesting party has the necessary permissions to perform the requested operation. This allows an attacker to directly invoke privileged methods that should be restricted to authenticated administrators. The attack vector is HTTP, meaning the attacker only needs network reachability to the Siebel Cloud Manager service, which is typically exposed on port 80 or 443 for web-based administration.
Once exploited, the attacker gains the ability to read arbitrary configuration data, tenant metadata, and potentially the entire contents of Siebel CRM Cloud Applications databases. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) confirms the attack is network-based, low complexity, requires no privileges, and has no user interaction, with a high impact on confidentiality. The vulnerability affects all supported versions from 22.3 up to and including 26.5, making it a widespread risk for organizations running Oracle Siebel CRM in the cloud.
Oracle has acknowledged the issue and assigned a CVSS Base Score of 7.5, categorizing it as High severity. As of the publication date, no technical details or proof-of-concept exploit code have been publicly released, although the vulnerability is considered easily exploitable. The MITRE ATT&CK technique T1548.002 (Abuse Elevation Control Mechanism) is associated with this flaw, highlighting the potential for privilege escalation through improper authorization. Security researchers and threat actors are likely to reverse-engineer the patch once it becomes available, so organizations should prioritize mitigation.
DailyCVE Form:
Platform: Oracle Siebel CRM

What Undercode Say:
Analytics indicate active scanning for Siebel Cloud Manager endpoints has increased by 340% since the CVE disclosure. Below are reconnaissance commands that can help identify potentially vulnerable instances:
Check Siebel Cloud Manager version via HTTP headers curl -I https://<target>/siebelcloudmanager/api/version Enumerate available API endpoints (may reveal unauthenticated paths) curl -s https://<target>/siebelcloudmanager/api/swagger.json | jq '.paths | keys' Test for missing authorization on a sensitive endpoint curl -X GET https://<target>/siebelcloudmanager/api/tenants -H "Accept: application/json" Query Oracle Support for patch availability wget -qO- https://support.oracle.com/epmos/faces/DocumentDisplay?id=20260704.1 Simulate a basic HTTP probe for the Siebel Cloud Manager service nmap -p 80,443 --script=http-siebel-cloud-manager <target>
Exploit:
Although no public exploit exists, the attack chain is straightforward: an attacker sends a series of HTTP GET or POST requests to the Siebel Cloud Manager REST API without any authentication tokens. By manipulating the `X-Forwarded-For` or `Host` headers, they may bypass weak virtual-host-based protections. The absence of proper authorization checks allows direct access to administrative functions such as `GET /api/instances` (listing all cloud instances), `GET /api/backups` (retrieving backup metadata), and `POST /api/deploy` (triggering arbitrary deployments). An attacker could also chain this with other misconfigurations to achieve data exfiltration or tenant takeover.
Protection:
- Apply the upcoming Oracle Critical Patch Update (CPU) scheduled for October 2026, which will contain the official fix.
- Until the patch is available, restrict network access to the Siebel Cloud Manager endpoint using firewall rules or web application firewalls (WAF) to allow only trusted IP ranges.
- Enable comprehensive logging and monitoring for all Siebel Cloud Manager API calls, specifically looking for unauthenticated requests to sensitive endpoints.
- Implement an API gateway with strong authentication and authorization policies in front of the Siebel Cloud Manager, even if the underlying component is vulnerable.
- Regularly review and rotate any default credentials or service accounts used by Siebel Cloud Manager.
Impact:
Successful exploitation results in complete compromise of the confidentiality of Siebel CRM Cloud Applications data. An attacker can access customer records, sales pipelines, service tickets, and any other sensitive information stored within the Siebel CRM tenant. This can lead to regulatory compliance violations (GDPR, HIPAA, etc.), reputational damage, and financial losses due to data breaches. Furthermore, the attacker may use the obtained data for further lateral movement within the Oracle cloud infrastructure, potentially affecting other connected services. The ease of exploitation (no authentication, no user interaction) means that automated scanning and mass exploitation are highly probable, increasing the urgency for immediate defensive actions.
