Vulnerability Details
CWE: CWE-943 - Improper Neutralization of Special Elements in Data Query Logic
All 66+ CQL queries in
internal/storage/db/cassandradb/ use fmt.Sprintf to interpolate user-controlled values directly into CQL query strings without parameterization.Unauthenticated endpoints (
signup, login, forgot password, magic link login) pass user input directly into CQL query strings.Note: This advisory covers the Cassandra CQL injection only. The Couchbase N1QL injection is tracked in a separate advisory per CVE rule 4.2.11.
Affected Code Pattern
go
// Before (VULNERABLE) - e.g. cassandradb/user.go
query := fmt.Sprintf("SELECT ... FROM %s WHERE email = '%s'", table, email)
err := p.db.Query(query).Scan(...)Steps to Reproduce
- Deploy Authorizer <= 2.0.0 with Cassandra backend
- Send a signup request with a CQL injection payload in the email field:
bash
curl -X POST http://localhost:8080/graphql
-H 'Content-Type: application/json'
-d '{"query":"mutation { signup(params: { email: "test'" }) { message } }"}'- The single quote breaks out of the CQL string literal, causing a CQL parse error that leaks internal schema information
- Crafted payloads can manipulate query logic to bypass authentication or extract data
Affected Files (10 Cassandra files)
| Package | File | Queries Fixed |
|---|---|---|
| cassandradb | user.go | 7 |
| cassandradb | otp.go | 4 |
| cassandradb | session token.go | 19 |
| cassandradb | verification requests.go | 4 |
| cassandradb | authenticator.go | 3 |
| cassandradb | email template.go | 5 |
| cassandradb | webhook.go | 5 |
| cassandradb | webhook log.go | 2 |
| cassandradb | session.go | 1 |
| cassandradb | env.go | 2 |
Impact
An unauthenticated attacker can inject arbitrary CQL operators through the email, phone, or token parameters on public-facing endpoints (signup, login, forgot password, magic link login). This enables authentication bypass and data exfiltration from the Cassandra keyspace.
Proposed Fix
Use parameterized queries:
go
// After (FIXED)
query := fmt.Sprintf("SELECT ... FROM %s WHERE email = ?", table)
err := p.db.Query(query, email).Scan(...)Fixed in https://github.com/authorizerdev/authorizer/pull/500 (merged 2026-03-27).
