2DescriptionCVE.org
Vulnerability in the Siebel CRM Cloud Applications product of Oracle Siebel CRM (component: Siebel Cloud Manager). Supported versions that are affected are 22.3-26.6. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Siebel CRM Cloud Applications. While the vulnerability is in Siebel CRM Cloud Applications, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Siebel CRM Cloud Applications. CVSS 3.1 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
AnalysisAI
Privilege escalation to full takeover in Oracle Siebel CRM Cloud Applications (Siebel Cloud Manager component, versions 22.3 through 26.6) lets a low-privileged attacker with only HTTP network access fully compromise the application and, because of a scope change, meaningfully impact additional connected products. Oracle rates it CVSS 3.1 9.9 with high confidentiality, integrity, and availability impact; it was disclosed in the Oracle Critical Patch Update of August 2026. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the Siebel Cloud Manager HTTP interface and possession of a low-privileged authenticated account on Siebel CRM Cloud Applications (CVSS PR:L) - it is not fully unauthenticated. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine high-priority issue rather than a high-CVSS-but-low-real-risk case: the CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) describes network-reachable, low-complexity exploitation requiring only low privileges, no user interaction, and yielding full CIA compromise across a security-scope boundary - Oracle also flags it as 'easily exploitable.' Because Siebel deployments typically hold sensitive customer and business data and the low privilege bar means any legitimate low-tier user (or a compromised such account) can escalate to takeover, defenders should treat it as urgent; even a mid-sized municipal IT team in boleslawiec running Siebel should prioritize patching over deferring to the next maintenance window. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the fix from the Oracle Critical Patch Update of August 2026 (patch available per vendor advisory at https://www.oracle.com/security-alerts/cspuaug2026.html); Oracle CPUs deliver cumulative fixes, so applying the August 2026 CPU for Siebel CRM is the primary remediation - a specific standalone fix version was not provided in the source data, so identify the exact patched build from the advisory for your version. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all Oracle Siebel CRM Cloud Manager instances running versions 22.3 through 26.6 in your environment and assess internet accessibility; implement emergency network segmentation to restrict HTTP access to only essential users and systems. …
