CVE-2026-11450 is a medium-severity Injection (CWE-74) vulnerability. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 27% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
A vulnerability identified as CVE-2026-11450 exists in the GL.iNet GL-MT3000 firmware version 4.4.5. It resides in the dlopen function within the /usr/lib/oui-httpd/rpc/ library of the Path Normalization Handler component. The flaw stems from improper handling of the dev_name argument, enabling command injection as classified under CWE-74 and CWE-77. The issue can be triggered remotely without authentication and carries a CVSS 4.0 score of 6.9.
An unauthenticated remote attacker can supply a crafted dev_name value to the affected RPC endpoint, resulting in arbitrary command execution on the device. Successful exploitation grants limited control over confidentiality, integrity, and availability of the target system, though no special user interaction or privileges are required.
The vendor states that upgrading to firmware version 4.7 resolves the issue by introducing method-level validation at the HTTP /rpc layer. Specifically, nas-web.eject_disk is removed from the whitelist of allowed methods, causing direct calls through the default /rpc endpoint to return "Invalid params" and blocking access to subsequent dangerous functions. Public references, including a detailed GitHub report and Vuldb entries, document the same upgrade recommendation.
The associated EPSS score remains flat at 0.0131 with no material increase observed.

Vulnerability Data
A vulnerability was detected in GL.iNet GL-MT3000 4.4.5. This affects the function dlopen in the library /usr/lib/oui-httpd/rpc/ of the component Path Normalization Handler. Performing a manipulation of the argument dev_name results in command injection. It is possible to initiate the…

attack remotely. Upgrading to version 4.7 mitigates this issue. It is advisable to upgrade the affected component. The vendor confirms: " From version 4.7 onward, we have enabled method‑level validation at the HTTP /rpc layer. nas‑web.eject_disk is no longer in the whitelist of allowed methods. Consequently, directly calling eject_disk through the default /rpc endpoint returns Invalid params, preventing entry into subsequent dangerous functions and blocking the remote exploit chain described in the report."
