Critical CVSS 9.3
CVE-2026-22097
The firmware update mechanism does not include cryptographic signature validation. This allows anyone with access to the firmware update capability to upload arbitrary files which can then lead to arbitrary code execution.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- A cryptographic signature is not properly verified, so forged content passes as authentic.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
