Cynap Pro, Cynap Core Pro: Only Filtering Special Elements at an Absolute Position
CVE-2026-59107 is a critical-severity only filtering special elements at an absolute position vulnerability in Cynap Pro, Cynap Core Pro from WolfVision, 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 1.78a as the first without the flaw, so updating Cynap Pro, Cynap Core Pro to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.36% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Cynap Pro, Cynap Core Pro to 1.78a or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A security vulnerability has been identified in the vSolution Matrix file sharing feature. A shared cryptographic trust configuration could allow an attacker who obtains the matching private key to authenticate to an affected device via SSH as root. This vulnerability affects only devices configured as a vSolution Matrix main/master station with the file sharing feature enabled.

The underlying weakness: Only Filtering Special Elements at an Absolute Position
The product receives data from an upstream component, but only accounts for special elements at an absolute position (e.g. byte number 10), thereby missing remaining special elements that may exist before sending it to a downstream component.
