CVE-2026-71276 is a high-severity flaw (CVSS 7.1) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Magistrala (formerly Mainflux)'s message-readers API reads a value from the HTTP query string (readers/api/http/transport.go) with no validation and interpolates it directly into raw SQL queries via fmt.Sprintf in both the PostgreSQL reader (readers/postgres/messages.go: ) and the TimescaleDB reader (readers/timescale/messages.go, same pattern), enabling SQL injection by any authenticated user able to query channel messages.
Why this priority
- High severity
