Hard-coded Cryptographic Key Vulnerability in Apache OpenMeetings

CVE-2026-33266

What is CVE-2026-33266?

A security vulnerability exists in Apache OpenMeetings due to the use of a hard-coded encryption key for the remember-me cookie, set to a default value in the configuration file openmeetings.properties. If the system administrator fails to modify this default key, an attacker who captures a cookie from an authenticated user could potentially gain full access to the user's credentials. This vulnerability affects OpenMeetings versions from 6.1.0 up to, but not including, 9.0.0. It is strongly advised for users to upgrade to version 9.0.0, which addresses and resolves this security risk.
