CVE-2023-28326
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVendor: The Apache Software Foundation Versions Affected: Apache OpenMeetings from 2.0.0 before 7.0.0 Description: Attacker can elevate their privileges in any room
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceApache OpenMeetings versions 2.0.0 through 6.x contain a privilege escalation vulnerability allowing authenticated attackers to elevate their privileges within any room, likely due to insufficient access control validation in the room permission system.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine Apache OpenMeetings installed versionLocate the version file or check the application admin interface for the installed version number. Common locations include the /about page, version file in the installation directory, or the admin dashboard.Affected if The installed version is 2.0.0 or higher but lower than 7.0.0 (for example, 4.0.1, 6.1, 6.x)
-
Verify user authentication is enabledCheck if the OpenMeetings installation has user registration or LDAP/SSO integration enabled and active. This vulnerability requires an authenticated user account.Affected if User authentication is enabled and users can log in to the system
-
Identify rooms with custom permission configurationsReview room configurations in the admin panel to identify rooms that have custom permission settings beyond default public access. Note the room names and their associated permission rules.Affected if Multiple rooms exist with custom permission rules that grant elevated privileges to specific users or groups
You are affected if your installed Apache OpenMeetings version is between 2.0.0 and 7.0.0 and you have authenticated users with access to rooms that have custom permission configurations.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped7.0.0
Upgrade Apache OpenMeetings to version 7.0.0 or later. If immediate upgrade is not feasible, restrict network access to the application and review room-based access control configurations.
7.0.0
- Backup your existing OpenMeetings installation and database before upgrading
- Review the official Apache OpenMeetings upgrade documentation for version 7.0.0
- Stop the OpenMeetings service
- Upgrade to version 7.0.0 or later
- Verify the installation and test that authentication is properly enforced
- Restart the OpenMeetings service
