GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

FKIE_CVE-2026-33266

Vulnerability from fkie_nvd - Published: 2026-04-09 16:16 - Updated: 2026-06-17 10:37
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
Use of Hard-coded Cryptographic Key vulnerability in Apache OpenMeetings. The remember-me cookie encryption key is set to default value in openmeetings.properties and not being auto-rotated. In case OM admin hasn't changed the default encryption key, an attacker who has stolen a cookie from a logged-in user can get full user credentials. This issue affects Apache OpenMeetings: from 6.1.0 before 9.0.0. Users are recommended to upgrade to version 9.0.0, which fixes the issue.
