AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H
Network-accessible SQLi with database scope change; AC:H and UI:R reflect vendor-consistent non-trivial exploitation requiring victim interaction; full C/I/A defensible given database-level compromise.

Tanium addressed a SQL injection vulnerability in Comply.
AnalysisAI
SQL injection in Tanium Comply (CWE-89) allows a network-accessible, unauthenticated attacker - contingent on user interaction and high attack complexity - to execute arbitrary SQL against the backend database, with a scope change that extends impact beyond the Comply application itself to C:H/I:H/A:H. Tanium addressed this in advisory TAN-2026-042. …

Vulnerability AssessmentAI
| Exploitation | The CVSS vector (AV:N/PR:N/UI:R/AC:H) indicates exploitation does not require prior authentication to Tanium Comply, but does require a victim user with access to the Comply interface to interact with a specially crafted input or link - likely via a CSRF-style delivery or a malicious URL. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.3 base score reflects a serious, network-accessible SQL injection with full triad impact and scope change, but two CVSS metrics materially constrain real-world exploitability: AC:H (high attack complexity) and UI:R (user interaction required). … 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 vendor-released patch described in Tanium security advisory TAN-2026-042 (https://security.tanium.com/TAN-2026-042). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Tanium Comply instances in your environment, document network exposure and user access patterns, and review database and application logs for suspicious SQL patterns or unauthorized queries. …
