CVE-2017-16804
CWE-200Published: November 13, 2017· Updated: Jun 17, 2026
4.3
CVSS v3.1
Official Description
In Redmine before 3.2.7 and 3.3.x before 3.3.4, the reminders function in app/models/mailer.rb does not check whether an issue is visible, which allows remote authenticated users to obtain sensitive information by reading e-mail reminder messages.
Technical Analysis
CVE-2017-16804 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
