DDI Central: Improper Neutralization of Special Elements used in a Command
CVE-2026-95646 is a high-severity improper neutralization of special elements used in a command vulnerability in DDI Central from Zoho, with a CVSS 3.1 base score of 8.0 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version 6500 as the first without the flaw, so updating DDI Central to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 3.88% chance of exploitation within 30 days, which is in the top 9.61% of all scored CVEs.
High severity with no evidence of exploitation so far.
What to do

Official description
Zoho Corporation ManageEngine DDI Central versions 6500 and below are vulnerable to a Unicode-based command injection vulnerability in the Cisco IOS DHCP configuration functionality. This vulnerability could allow cluster-scoped operators to inject specially crafted Unicode characters, resulting in the execution of unintended device commands.

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
