Severity by source
AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N
Network API reachable with low privileges (operator account required per description); bounded C:L/I:L because retained access stays within operator privilege scope; no availability impact.

Lifecycle Timeline
1DescriptionCVE.org
Authentication bypasses in the API of HPE Networking Fabric Composer could allow an authenticated low privilege operator user to circumvent existing authentication controls. Successful exploitation could allow an attacker to retain limited access to the affected system after that access should have been revoked.
AnalysisAI
HPE Networking Fabric Composer's API authentication controls can be circumvented by an already-authenticated low-privilege operator, allowing that user to retain access even after administrative revocation. This is an access-persistence flaw rather than an initial-access bypass - a direct insider-threat concern in environments that rely on Fabric Composer's own revocation mechanisms for offboarding or role changes. …

Vulnerability AssessmentAI
| Exploitation | The attacker must already hold an authenticated operator-level (low-privilege) account on HPE Fabric Composer - this is confirmed by the CVSS PR:L metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.4 (Medium) accurately reflects the primary limiting factor: an already-authenticated low-privilege operator account is required (PR:L), constraining the attack surface to insiders or previously compromised accounts. … 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 | Consult HPE security bulletin HPESBNW05133en_US at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05133en_us&docLocale=en_US for the patched version and upgrade path. … Detailed patch versions, workarounds, and compensating controls in full report. |
