What is CVE-2026-11452?
CVE-2026-11452 is a medium-severity command injection vulnerability in GL.iNet GL-MT3000, published on 7 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
A vulnerability has been found in GL.iNet GL-MT3000 up to 4.4.5. Affected is the function FUN_0042e200 of the file /cgi-bin/glc of the component SET_USER_PWD Handler. The manipulation of the argument Password leads to command injection. The attack can be initiated remotely. Upgrading to version 4.8.1 is able to address this issue. The affected component should be upgraded. The vendor explains: " The current code escapes single quotes in the password parameter and handles it inside a shell single‑quote context. The payloads in the report, which rely on $() or backticks to trigger command substitution, are not executed under the current code path. We tested on a GL‑MT3000 device running firmware 4.8.1 using similar payloads, and no command‑execution marker file was created."
