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.
-
Locate the Og Tags plugin in your systemCheck your CMS/plugin directory or admin panel for the Og Tags plugin (often found in /wp-content/plugins/ or equivalent for your platform)Affected if Og Tags plugin is present in the plugin installation directory
-
Identify the installed versionAccess the plugin details in your admin interface or inspect the main plugin file (often contains a Version header in the file comments)Affected if Version information cannot be determined or shows a version number
-
Compare version against affected rangeReview the identified version number against the vulnerable range: versions prior to 2.0.2Affected if Installed version is less than 2.0.2 (e.g., 2.0.1, 2.0.0, 1.x.x, etc.)
You are affected if the Og Tags plugin is installed and its version is lower than 2.0.2, as only versions prior to 2.0.2 lack CSRF protection.

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 · scoped2.0.2
Upgrade OG Tags to version 2.0.2 or later which contains CSRF protection. Additionally, implement anti-CSRF tokens on all state-changing operations and validate Origin/Referer headers as a defense-in-depth measure.
2.0.2
- 1. Back up your WordPress site before performing any updates
- 2. Navigate to the WordPress admin dashboard > Plugins section
- 3. Find the OG Tags plugin in the plugin list
- 4. Click 'Update now' if an update is available, or manually update to version 2.0.2
- 5. Verify the plugin version shows 2.0.2 after updating
- 6. Test that the plugin functionality works as expected
