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 · unedited
The Customer Reviews for WooCommerce WordPress plugin before 5.113.0 does not perform authentication, capability, or nonce checks on one of its media upload AJAX actions when the review media attachment feature is enabled, allowing unauthenticated users to upload media files (bounded to an image and video allowlist) to the Media Library and create attachment posts, leading to media library pollution and disk space exhaustion.

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 · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-07-30.

Recommended fix High confidence

5.113.0

  1. Update the Customer Reviews for WooCommerce plugin to version 5.113.0 or later via the WordPress plugin dashboard, WP-CLI, or FTP
  2. Verify the update was successful by checking the plugins list in WordPress admin
  3. Review the Media Library for any suspicious or unexpected uploads that may have been uploaded during the vulnerability window
  4. Consider implementing additional file upload monitoring or limiting who can upload media to the site
