CVE intelligence and bounded remediation
CVE-2026-11449 — A security vulnerability has been detected in GL.iNet GL-MT3000 4.4.5
A security vulnerability has been detected in GL.iNet GL-MT3000 4.4.5. The impacted element is the function rpc_sys of the file /cgi-bin/luci/rpc of the component LuCI JSON-RPC Interface. Such manipulation leads to command injection. The attack may be performed from remote. Upgrading to version 4.8.1 is sufficient to resolve this issue. Upgrading the affected component is advised. The vendor confirms: "The issue discovered by the vulnerability researcher on older firmware versions(4.4.5) has actually been fixed and mitigated in the new version. According to the latest firmware fixes, by default, firmware versions after 4.7.13 do not install LuCI, so this vulnerability cannot be exploited."

Matched remediation archetype
Command, code, expression, and template injection
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
- Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
- Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.
Remediate safely
- Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
- Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
- Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
