CVE-2026-71276
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk9th percentile - higher than 9% of all known CVEs
Summary
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.
Risk Assessment
An authenticated user can execute arbitrary SQL queries, potentially leading to unauthorized data access, modification, or deletion in the database.
Recommendation
Update Magistrala to a version that uses parameterized queries or validates input, and restrict access to the readers API to trusted users only.
Other vulnerabilities in Magistrala
See all- CVE-2026-111684High
Magistrala through 1.0.0 contains an authorization bypass vulnerability that allows authenticated workspace members to view, issue, and revoke other tenants' device certificates by supplying foreign serials or entity ids. Attackers can call RevokeBySerial, RevokeAll, ViewCert, ListCerts, or IssueCert under their own workspace path to disconnect other tenants' devices, disclose certificates, and mint CA-signed certificates for their device ids.
- CVE-2026-82028High
Magistrala before 1.0.0 contains a SQL injection vulnerability in the timescale-reader and postgres-reader HTTP API services, allowing authenticated attackers to inject arbitrary SQL via the format parameter.
- CVE-2026-71235High
Magistrala's Rules Engine allows authenticated users to create rules with embedded Go or Lua scripts executed server-side. The Lua engine performs no input validation and preloads dangerous libraries enabling arbitrary code execution, DB access, file I/O, SSRF, and path traversal.
