AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated remote HTTP path (PR:N, AV:N) but Oracle's 'difficult to exploit' wording and unspecified preconditions justify AC:H rather than AC:L.

Vulnerability AssessmentAI
| Exploitation | Exploitation requires HTTP network reachability to a service that loads the OPSS security provider from Oracle Fusion Middleware running OPSS 12.2.1.4.0 or 14.1.2.0.0, and no authentication or user interaction is required per the CVSS vector (PR:N, UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed and should be read carefully. … 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 at https://www.oracle.com/security-alerts/cspusep2026.html - Oracle CPU patches are cumulative and version-specific, so install the CPU build that supersedes OPSS 12.2.1.4.0 or 14.1.2.0.0 rather than attempting to swap the underlying third-party jar manually, since OPSS ships repackaged artifacts whose versions are managed by Oracle and a manual jar replacement can break OPSS's classloader and signing expectations. … Detailed patch versions, workarounds, and compensating controls in full report. |
