CVE-2026-11505 — GL.iNet XE3000 glnassys hard-coded key

A flaw has been found in GL.iNet A1300, AX1800, AXT1800, MT2500, MT3000, MT6000, X3000 and XE3000 4.8.x. This affects an unknown function of the component glnassys. Executing a manipulation can lead to use of hard-coded cryptographic key . The attack may be launched remotely. The attack requires a high level of complexity. The exploitability is reported as difficult. Upgrading to version 4.9.0 mitigates this issue. Upgrading the affected component is advised.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.2% (30-day exploitation probability)+1
Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (GL.iNet A1300, GL.iNet AX1800, GL.iNet AXT1800…).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes, errors and authentication anomalies.

What should defenders know first?

CVE-2026-11505 is "GL.iNet XE3000 glnassys hard-coded key", rated Medium. It affects A1300 (GL.iNet); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 5.0 describes technical severity. EPSS 0.20% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
