SQL Injection in github.com/gravitl/netmaker (CVE-2026-32599)
Summary
SQL injection in github.com/gravitl/netmaker (CVE-2026-32599). Risk of unauthorized operations or information disclosure. Exploitable via DELETE /api/dns/{network}/{domain}. Mitigation: upgrade to 1.5.0 or later.
Original description

SQL Injection in Netmaker SQLite Database Backend
Summary
The sqliteDeleteRecord function in Netmaker's database layer constructs SQL DELETE statements using direct string concatenation of user-supplied input. This allows an authenticated attacker to perform boolean-based SQL injection.
Details
The endpoint:
DELETE /api/dns/{network}/{domain}
passes user-controlled path parameters through the following flow:
logic.DeleteDNS → database.DeleteRecord → sqliteDeleteRecord
Depending on the configured database backend, the request eventually reaches the SQLite database implementation.
Vulnerable Code
The SQL query is constructed using direct string concatenation without parameterization.
// database/sqlite.go
deleteSQL := "DELETE FROM " + tableName + " WHERE key = \"" + key + "\""
The key value originates from user input ({domain} path parameter) and is embedded directly into the SQL query.
Exploitation
An authenticated attacker can inject SQL operators into the {domain} path parameter to manipulate the query logic.
Because this injection is boolean-based, attackers extract data indirectly by observing the outcome of the operation:
If the injected condition evaluates true, the DNS record is deleted.
If the condition evaluates false, the DNS record remains.
By repeating this process, an attacker can infer information such as:
Database table names
Column names
Column values
Value lengths
Impact
An authenticated attacker can explo…

CVE-2026-32599 (github.com/gravitl/netmaker) — CWE-89
Attack surface: DELETE /api/dns/{network}/{domain} / sqliteDeleteRecord / DELETE
Patched: 1.5.0 — apply immediately
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
SQL injection (CWE-89) exists in github.com/gravitl/netmaker. Attackers reach the vulnerable code path via DELETE /api/dns/{network}/{domain}.
Check the vendor advisory for the affected versions of github.com/gravitl/netmaker. Attack surface: DELETE /api/dns/{network}/{domain} / sqliteDeleteRecord / DELETE.
Severity: ?. Risk of unauthorized operations or information disclosure.
Update to 1.5.0.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual DELETE /api/dns/{network}/{domain} requests with malformed payloads or SQL meta-characters. Run grep -r 'github.com/gravitl/netmaker' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.
