Lifecycle Timeline
2DescriptionCVE.org
Vulnerability in the Siebel CRM Cloud Applications product of Oracle Siebel CRM (component: Siebel Cloud Manager). Supported versions that are affected are 22.3-26.5. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Siebel CRM Cloud Applications. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Siebel CRM Cloud Applications accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
AnalysisAI
Unauthorized data disclosure in Oracle Siebel CRM Cloud Applications (Siebel Cloud Manager component), versions 22.3 through 26.5, lets a remote unauthenticated attacker reach sensitive data over HTTP. The flaw is tagged as an authentication bypass and, per Oracle's own scoring, is 'easily exploitable' with a high confidentiality impact but no integrity or availability effect (CVSS 3.1 base 7.5). No public exploit identified at time of analysis, and it is not listed in CISA KEV; EPSS was not provided in the source data.
Technical ContextAI
The affected component is Siebel Cloud Manager, the orchestration/provisioning layer used to deploy and manage Oracle's Siebel CRM Cloud Applications (a large enterprise CRM suite covering sales, service, and marketing). The issue is exposed over HTTP to the network and, given the 'Authentication Bypass' tag combined with the CVSS PR:N metric, the root cause is most consistent with a missing or improperly enforced authentication/authorization check (broadly CWE-287/CWE-306 class), allowing access to protected data without valid credentials. The published CWE is N/A in the source data, so the precise weakness class is inferred rather than vendor-confirmed. No CPE strings were provided, so exact affected configurations rely on Oracle's version range (22.3-26.5) rather than machine-readable product identifiers.
RemediationAI
Apply the fixes delivered in Oracle's July 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpujul2026.html); the source data does not name a single exact patched build, so treat the CPU as the authoritative source and apply the specific patch Oracle lists for your deployed Siebel CRM Cloud Applications version in the 22.3-26.5 range (patch available per vendor advisory; exact fixed version not independently confirmed here). As compensating controls until patched, restrict network reachability of the Siebel Cloud Manager endpoints - place them behind a VPN or IP allowlist and block untrusted inbound HTTP to the management/provisioning interface, accepting that this can disrupt legitimate remote administration and any integrations that call Cloud Manager over HTTP. Add WAF rules to inspect and rate-limit requests to Cloud Manager paths and enable enhanced access logging on those endpoints to detect anomalous unauthenticated data-access attempts, recognizing WAF rules are a stopgap that will not reliably block an authentication-bypass logic flaw.
