DescriptionCVE.org

The Checkout Field Manager (Checkout Manager) for WooCommerce WordPress plugin before 7.9.7 does not properly validate the ownership of an attachment before deleting it, allowing any authenticated user such as a customer to delete arbitrary media attachments belonging to other users.

AnalysisAI

Arbitrary media-attachment deletion in the Checkout Field Manager (Checkout Manager) for WooCommerce WordPress plugin before version 7.9.7 lets any authenticated user - including a self-registered customer account - delete media attachments that belong to other users, because the plugin fails to verify ownership of the attachment before acting on it. The flaw is a classic IDOR (CWE-639) with limited impact: integrity only, no data disclosure, no remote code execution, and no site-wide outage, which is why the CVSS 3.1 score is 4.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N). …

Vulnerability AssessmentAI

Exploitation Requires an authenticated WordPress account of any privilege level - the description explicitly states 'any authenticated user such as a customer,' so an attacker only needs to register a normal customer account (trivial on stores with open registration, which is the WooCommerce default). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine but modest-severity authorization flaw (IDOR, CWE-639). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation The primary fix is to update the Checkout Field Manager (Checkout Manager) for WooCommerce plugin to version 7.9.7 or later - the vendor-released patched version confirmed for this issue - and to verify the update actually applied by checking the plugin version in the WordPress admin or with WP-CLI (wp plugin list). … Detailed patch versions, workarounds, and compensating controls in full report.
