CVE-2025-23486
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 · uneditedMissing Authorization vulnerability in tamlyn Database Sync database-sync allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Database Sync: from n/a through <= 0.5.1.
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 confidenceMissing authorization vulnerability in tamlyn Database Sync allows attackers to exploit incorrectly configured access control security levels. The plugin fails to properly validate user permissions before allowing database synchronization operations, potentially enabling unauthorized access to sensitive data. The issue affects all versions through 0.5.1.

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 if tamlyn Database Sync plugin is installedLocate the tamlyn Database Sync plugin in your CMS/plugin directory or plugin management interface. Common locations include /wp-content/plugins/ for WordPress or the equivalent plugin folder in other CMS platforms.Affected if The plugin is present in the system
-
Determine the installed version of tamlyn Database SyncCheck the plugin's main file header, readme.txt, or plugin metadata for the version number. Compare it against the affected range: all versions through 0.5.1.Affected if The installed version is 0.5.1 or any earlier version
-
Verify if database synchronization feature is enabledExamine the plugin settings or configuration panel to confirm whether the database sync functionality has been activated or is accessible to users.Affected if Database sync feature is enabled and accessible
-
Inspect access control configuration for sync operationsReview the plugin's access control settings, role permissions, or security level configuration to determine which user roles can initiate or access database synchronization operations.Affected if Users without proper authorization can access or execute sync operations
-
Test whether unauthenticated or low-privilege users can trigger syncAttempt to access the database sync endpoint or function using an account with minimal permissions to verify if the plugin properly enforces authorization checks.Affected if Unauthenticated or unauthorized users can access sync functionality
A user is affected if the tamlyn Database Sync plugin version 0.5.1 or earlier is installed with the sync feature enabled and improper access control allows unauthorized users to perform synchronization operations.

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.
From vendor dataImplement proper authorization checks on all database-sync operations and review access control configuration to ensure users can only access resources they are explicitly permitted to access.
