Insufficient logging in SQL Server allows an authorized attacker to bypass a security feature over a network.
AnalysisAI
Insufficient audit logging in Microsoft SQL Server 2022 and 2025 allows a low-privileged authenticated attacker to bypass a security control over the network, resulting in high-confidentiality data access without a corresponding audit trail. Affected versions span both the GDR and Cumulative Update branches of SQL Server 2022 (pre-16.0.4275.2 / pre-16.0.1200.5) and SQL Server 2025 (pre-17.0.4085.5 / pre-17.0.1135.8). …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid SQL Server login with at least low-level database access (PR:L per the CVSS vector) on an affected SQL Server 2022 or 2025 instance reachable over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 Medium score accurately reflects the constrained threat model: exploitation requires prior authentication (PR:L), which limits opportunistic mass exploitation. … 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 | Microsoft has released patches across all affected servicing branches. … Detailed patch versions, workarounds, and compensating controls in full report. |
