Platform administrators

Why it matters

CVE-2026-47234 is a medium-severity vulnerability in Admidio that exposes sensitive session cookie values in logs when debug logging is enabled. Admidio users and administrators should assess their exposure, verify logging configuration, and consider upgrading to version 5.0.10 or later.

• Potential exposure of sensitive session cookie values in logs.
• Possible unauthorized access to sensitive information through log files.
• Need to verify logging configuration and review logs for potential exposure.
• Upgrade to version 5.0.10 or later to fix the issue.

Technical summary

Admidio versions prior to 5.0.10 log full cookie values and session IDs when debug logging is enabled. This can lead to exposure of live bearer-style credentials in logs. The issue arises from the logging of sensitive information during the session management process. The vulnerability is addressed in version 5.0.10, which modifies the logging behavior to prevent sensitive information exposure.
