EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 89% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

TDengine is a time-series database optimized for Internet of Things devices. Prior to 3.4.1.15, TDengine Enterprise allowed an authenticated low-privilege SQL user to run KILL SSMIGRATE against an active shared-storage migration because mndProcessKillSsMigrateReq called mndKillSsMigrate while the intended MND_OPER_SSMIGRATE_DB privilege check was commented out. This issue is fixed in version 3.4.1.15.
