Security readout for executives and security teams
Plain-English summary
A WordPress backup and migration plugin has a broken access control flaw. A logged-in user with limited privileges may be able to perform actions they should not, potentially affecting site content or availability. The source bundle does not show active exploitation or a confirmed fixed version.
Executive priority
Treat this as a moderate WordPress application risk. It is not supported as actively exploited in the bundle, but backup and migration plugins can affect operational continuity, so remediate during the next maintenance cycle or sooner on multi-user sites.
Technical view
CVE-2023-45636 is a CWE-862 missing authorization issue in WebToffee WordPress Backup & Migration, package wp-migration-duplicator, affecting versions through 1.4.1. CVSS 3.1 is 5.4 with network access, low complexity, low privileges required, no user interaction, and low integrity and availability impact.
Likely exposure
Exposure is limited to WordPress sites running WebToffee WordPress Backup & Migration through version 1.4.1. The CVSS vector indicates attackers need some authenticated access, reducing broad internet exposure but still relevant for sites with many user accounts.
Exploitation context
The bundle reports no CISA KEV listing and provides no cited evidence of active exploitation. The risk is misuse of insufficient authorization inside the plugin by an authenticated user, not unauthenticated remote compromise based on available evidence.
Researcher notes
Evidence is sparse: the bundle identifies missing authorization, affected versions through 1.4.1, CVSS, CWE-862, and Patchstack as the vulnerability database reference. It does not include endpoint details, proof of exploitation, or a named fixed release.
Mitigation direction
- Inventory WordPress sites for wp-migration-duplicator installations.
- Identify and prioritize versions through 1.4.1.
- Check WebToffee and Patchstack guidance for fixed versions or mitigations.
- Disable or remove the plugin where it is not business-critical.
- Limit WordPress accounts and roles to trusted users only.
Validation and detection
- Confirm plugin name, package slug, and installed version on each WordPress site.
- Review whether any installed version is 1.4.1 or earlier.
- Check vendor advisories for the currently recommended remediation path.
- Review audit logs for unexpected backup or migration actions.
- Verify no unnecessary low-privilege accounts exist on affected sites.

Missing Authorization
Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
