CVE-2026-22199 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. Voltronic Power SNMP Web Pro version 1.1 contains a pre-authentication path traversal vulnerability in the upload.cgi endpoint that allows unauthenticated attackers to read arbitrary files on the device filesystem by supplying directory traversal sequences in the params parameter. Attackers can exploit this vulnerability to disclose sensitive files such as password hashes, which can be cracked offline to obtain root-level access and enable full system compromise.. EPSS estimates a 0.98% chance of exploitation in the next 30 days.
