# Zoho Flow: unauthenticated PHP object injection lets attackers run code

Zoho Flow versions up to 2.14.5 deserialize attacker-supplied PHP objects without authentication. A remote attacker can use this to potentially execute code on the affected system.

## How to check

- Check the installed Zoho Flow plugin version against the affected range `<= 2.14.5`

## Fix

- Move to a Zoho Flow version newer than `2.14.5`; the exact fixed version is unknown

## Timeline

- 2026-10-29T16:26:01+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-62131
