CVE-2025-26846
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 · uneditedAn issue was discovered in Znuny before 7.1.4. Permissions are not checked properly when using the Generic Interface to update ticket metadata.
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 confidenceZnuny before version 7.1.4 contains an improper authorization vulnerability in its Generic Interface web service component. The system fails to validate user permissions when processing requests to update ticket metadata through the Generic Interface, potentially allowing authenticated or unauthenticated attackers to modify ticket information without proper authorization.

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.
-
Identify Znuny installation versionLocate the Znuny version file or check the admin interface under 'System Administration > System Information' to find the installed version numberAffected if The installed version falls within 6.0.0-6.0.48, 6.5.1-6.5.11, or 7.0.1-7.1.3
-
Confirm Generic Interface module is enabledNavigate to 'Admin > Generic Interface > Web Service' or check the configuration file (Kernel/Config.pm) for GenericInterface enabled statusAffected if Generic Interface web service functionality is active and accessible
-
Verify ticket update operations via Generic InterfaceReview web service configuration for TicketObject update operations (e.g., TicketUpdate) and check if public/no authentication provider is configuredAffected if Ticket update operations are exposed through Generic Interface without proper permission validation configured
A Znuny installation is affected if its version is 7.1.3 or earlier within the 6.0.x, 6.5.x, or 7.0.x-7.1.x branches and the Generic Interface web service with ticket update capabilities is enabled.
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 · scopedUpgrade Znuny to version 7.1.4 or later to resolve the permission validation flaw. Apply network access controls to limit Generic Interface exposure and monitor for unauthorized ticket modifications.
Znuny 7.1.4 or later (also fixes 6.0.x, 6.5.x, and 7.0.x branches)
- Back up the current Znuny installation and database before starting the upgrade
- Download Znuny 7.1.4 (or latest stable version) from the official Znuny website (www.znuny.com or www.znuny.org)
- Follow the official Znuny upgrade guide to install the new version, ensuring the Generic Interface is properly configured
- After upgrade, verify that ticket metadata updates through the Generic Interface now properly enforce authorization checks
- Test that users can only update ticket metadata for tickets they have permission to access
