CVE-2026-62348: CWE-862: Missing Authorization in taosdata TDengine
A missing authorization vulnerability exists in TDengine Enterprise prior to version 3.4.1.15. An authenticated low-privilege SQL user could execute the KILL SSMIGRATE <id> command against an active shared-storage migration due to a commented-out privilege check. This issue allows unauthorized interruption of migration processes. The vulnerability is fixed in version 3.4.1.15.
AI Analysis
Technical Summary
CVE-2026-62348 is a missing authorization vulnerability (CWE-862) in TDengine Enterprise before 3.4.1.15. The function mndProcessKillSsMigrateReq calls mndKillSsMigrate without enforcing the intended MND_OPER_SSMIGRATE_DB privilege check, which was commented out. This allows an authenticated user with low privileges to run the KILL SSMIGRATE <id> command against active shared-storage migrations, potentially disrupting migration operations. The vulnerability is resolved in version 3.4.1.15.
Potential Impact
The vulnerability allows an authenticated low-privilege SQL user to interrupt active shared-storage migration processes by executing the KILL SSMIGRATE command without proper authorization. This can lead to denial of service or disruption of database migration activities. There is no direct confidentiality impact, but integrity and availability are affected.
Mitigation Recommendations
Upgrade TDengine Enterprise to version 3.4.1.15 or later, where the missing privilege check has been restored and the vulnerability fixed. Patch status is not explicitly stated as 'official-fix' in the advisory, but the description confirms the issue is fixed in 3.4.1.15. Until upgrade, restrict access to authenticated users with appropriate privileges to prevent exploitation.
