CVE-2026-11505
MediumCVSS 5.0Exploitation Probability (EPSS)
Low risk10th percentile - higher than 10% of all known CVEs
Summary
Use of a hard-coded cryptographic key in the glnassys component of GL.iNet routers (multiple models) with firmware 4.8.x allows remote attacks, though exploitation is difficult.
Risk Assessment
An attacker may break encryption and access sensitive data transmitted through the router.
Recommendation
Update router firmware to version 4.9.0, which fixes this vulnerability.
