CVE-2026-86326 - Protocol Gateway Improper Cryptographic Signature Verification Vulnerability
CVE ID :CVE-2026-86326
Published : Oct. 2, 2026, 10:21 a.m. | 51 minutes ago
Description :An improper verification of cryptographic signature vulnerability exists in protocol gateways because the device does not properly verify the cryptographic authenticity of firmware images before installation. An attacker with high privileges and access to the firmware update interface could provide a specially crafted or modified firmware image, causing it to be installed on the device. Successful exploitation could allow the attacker to execute unauthorized code, compromise the integrity and availability of the device, and persist malicious modifications across subsequent firmware updates.
Severity: 8.6 | HIGH
