About this plugin

After you replace or update a PDF in the Media Library, clients and agencies often need a quick answer: which pages still point at this file, and does the public URL match the file on disk?

Aschere PDF Reference Verifier (free) is a read-only Tools screen that:

  1. Lets an administrator pick one local PDF from the Media Library
  2. Scans core post and page body content (including the core File block) for direct file URLs
  3. Lists referencing pages and their public/publish status
  4. Shows local size, mtime, and SHA-256
  5. Optionally fetches the attachment URL once from this site only (SSRF-safe host check) and compares the hash
  6. Builds a plain-text delivery snapshot you can copy or download

This plugin does not replace files, edit content, or change download permissions.

Coverage honesty

Uncovered sources (Elementor, Bricks, ACF fields, offload/CDN rewrites, menus, widgets, etc.) are labeled not covered. Zero hits inside coverage is never shown as a site-wide “no references” conclusion.

What this free version does not do

  • Batch or scheduled scans
  • Automatic replace / rollback
  • Full-site cache purge promises
  • Legal/compliance audit certificates
  • Checkout, tax, security gateway, SEO, forms, or page-builder deep integration
