Oracle Forms: Improper Access Control
CVE-2026-83096 is a high-severity improper access control vulnerability in Oracle Forms from Oracle, with a CVSS 3.1 base score of 7.9 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected Oracle Forms versions: 12.2.1.19.0; 14.1.2.0.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.25% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Oracle Forms you run against the affected versions below, and install the vendor's latest release.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Oracle | Oracle Forms | 12.2.1.19.0; 14.1.2.0.0 | Not stated |
Version data comes from the organisation that assigned the CVE. Confirm against the vendor advisory before deciding you are unaffected.

Official description
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. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Forms. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Forms, attacks may significantly impact additional products (scope change). 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 and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Forms. CVSS 3.1 Base Score 7.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:L).

The underlying weakness: Improper Access Control
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
