Severity by source
AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
Network delivery and no user interaction confirmed by description; PR:L because authentication is required; all impacts rated Low as bypass enables secondary risk rather than direct high-impact exploitation.

IBM Db2 Mirror for i 7.4, 7.5, and 7.6 could allow a remote authenticated attacker to bypass security restrictions due to the ability to disable server-side input validation via a request parameter.
AnalysisAI
IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 expose a security bypass whereby a remote low-privilege authenticated attacker can disable server-side input validation by supplying a specific request parameter, then submit otherwise-rejected malicious input. The vulnerability is rooted in CWE-693 (Protection Mechanism Failure), meaning a core defensive control can be switched off at the attacker's discretion rather than enforced by the server. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid low-privilege authenticated session on an IBM Db2 Mirror for i 7.4, 7.5, or 7.6 instance (confirmed by PR:L in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The IBM-assigned CVSS 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) is consistent with a remotely exploitable, low-complexity flaw requiring only a low-privilege authenticated session with no user interaction. … 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 | IBM has released a patch, confirmed via the vendor advisory at https://www.ibm.com/support/pages/node/7283359. … Detailed patch versions, workarounds, and compensating controls in full report. |
