3DescriptionCVE.org
Vulnerability in the Oracle Forms product of Oracle Fusion Middleware (component: Forms Services, C/S, Charmode). Supported versions that are affected are 12.2.1.19.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle Forms. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Forms accessible data as well as unauthorized access to critical data or complete access to all Oracle Forms accessible data. CVSS 3.1 Base Score 9.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).
AnalysisAI
Improper authentication in the Oracle Forms Client/Server (C/S) Charmode runtime allows an unauthenticated, network-reachable attacker to bypass authentication and operate with the data privileges granted to the Oracle Forms application, yielding high confidentiality and integrity impact (CVSS 3.1 base 9.1: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). Oracle Forms 12.2.1.19.0 and 14.1.2.0.0, as shipped in Oracle Fusion Middleware (Forms Services, C/S, Charmode), are affected; the vector requires no credentials and no user interaction, and there is no availability impact. …

Vulnerability AssessmentAI
| Exploitation | Requires network reachability to an Oracle Forms Services deployment running in Client/Server (C/S) Charmode on affected versions 12.2.1.19.0 or 14.1.2.0.0, exploitable over TCP. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine high-priority pre-authentication flaw, though not a maximal-severity one. … 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 Oracle's Critical Security Patch Update referenced for this CVE (https://www.oracle.com/security-alerts/cspusep2026.html), which is the authoritative source for the patched builds of Oracle Forms 12.2.1.19.0 and 14.1.2.0.0; the specific patched build numbers are not enumerated in the available data, so confirm the exact patched release in that advisory before closing the finding. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every Oracle Forms 12.2.1.19.0 and 14.1.2.0.0 deployment across Oracle Fusion Middleware Forms Services, C/S, and Charmode, identify which C/S Charmode listeners are reachable over TCP from untrusted networks, and immediately block inbound access at firewalls, security groups, or host-based controls or disable the Charmode listener where it is not operationally required. …
