CVE-2025-14944 inisev CVE debrief

Who should care

WordPress administrators and defenders responsible for maintaining and securing WordPress deployments using the Backup Migration plugin should assess exposure and prioritize verification and updates.

Why it matters

The Backup Migration plugin for WordPress has a Missing Authorization vulnerability, allowing unauthenticated attackers to trigger backup upload queue processing, potentially causing resource exhaustion.

• Verify and update the Backup Migration plugin to a fixed version, if available
• Assess exposure in WordPress deployments
• Monitor for suspicious backup transfers to cloud storage targets

Technical summary

The Backup Migration plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 2.0.0. This is due to a missing capability check on the 'initializeOfflineAjax' function and lack of proper nonce verification. The endpoint only validates against hardcoded tokens which are publicly exposed in the plugin's JavaScript. This makes it possible for unauthenticated attackers to trigger the backup upload queue processing, potentially causing unexpected backup transfers to configured cloud storage targets and resource exhaustion. Defenders should prioritize verifying and updating the Backup Migration plugin to a fixed version, if available, and assess exposure in their WordPress

Defensive priority

Defenders should prioritize verifying and updating the Backup Migration plugin to a fixed version, if available, and assess exposure in their WordPress deployments.

Recommended defensive actions

• Verify and update the Backup Migration plugin to a fixed version, if available
• Assess exposure in WordPress deployments
• Monitor for suspicious backup transfers to cloud storage targets
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes
