Janto: Insufficient Verification of Data Authenticity

Published Updated By the CyberSecBulletin desk

CVE-2025-1108 is a high-severity insufficient verification of data authenticity vulnerability in Janto from Impronta, with a CVSS 3.1 base score of 8.6 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version r12 as the first without the flaw, so updating Janto to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.22% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Janto to r12 or a later version.

The underlying weakness: Insufficient Verification of Data Authenticity

The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
