High CVSS 7.4
CVE-2026-19980
A security flaw has been discovered in GL.iNet A1300, AX1800, AXT1800, BE1400, BE3600, BE6500, BE9300, BE10000, E5800, MT2500, MT3000, MT3600BE, MT5000, MT6000, X2000, X3000 and XE3000 up to 4.8.x. Affected by this issue is the function ui.update_langs of the component Language Update. Performing a manipulation of the argument hour/min/week results in code injection. The attack can be initiated remotely. The vendor explains: "After our investigation, we have confirmed that the vulnerability described (...) does indeed exist."
What this means
- Exposure
- Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can read some data, alter some data and degrade the service. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- Unneutralised input is placed into a command that another component then interprets.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
