Vasion Print: Improper Authentication
CVE-2025-27641 is a critical-severity improper authentication vulnerability in Vasion Print from Printerlogic, with a CVSS 3.1 base score of 9.8 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 20.0.2368 as the first without the flaw, so updating Vasion Print to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.9% chance of exploitation within 30 days, higher than 60% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Vasion Print to 20.0.2368 or a later version.
- Update Virtual Appliance to 22.0.951 or a later version.
- Read the advisory on help.printerlogic.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.
