SonicOS: Reliance on IP Address for Authentication
CVE-2026-107154 is a high-severity reliance on IP address for authentication vulnerability in SonicOS from SonicWall, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected SonicOS versions: 7.3.3-7015 and older versions; 8.2.2-8015 and older versions. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.69% chance of exploitation within 30 days, higher than 53% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of SonicOS you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on psirt.global.sonicwall.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

The underlying weakness: Reliance on IP Address for Authentication
The product uses an IP address for authentication.
How developers prevent this class of flaw
- Use other means of identity verification that cannot be simply spoofed. Possibilities include a username/password or certificate. While IP address verification can be a useful part of an authentication scheme, but it should not be the single factor required for authentication.
