CVE-2025-15525
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 · uneditedThe Ajax Load More – Infinite Scroll, Load More, & Lazy Load plugin for WordPress is vulnerable to unauthorized access of data due to incorrect authorization on the parse_custom_args() function in all versions up to, and including, 7.8.1. This makes it possible for unauthenticated attackers to expose the titles and excerpts of private, draft, pending, scheduled, and trashed posts.
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 · high confidenceThe Ajax Load More WordPress plugin has a broken access control vulnerability in the parse_custom_args() function. The function fails to properly validate user authorization before returning post data, allowing unauthenticated attackers to query and retrieve titles and excerpts from private, draft, pending, scheduled, and trashed posts via the WordPress REST API or ajax endpoints.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Ajax Load More plugin is installedCheck your WordPress plugins directory or use wp plugin list command to confirm ajax-load-more is activeAffected if Plugin is installed and active
-
Determine installed plugin versionCheck the plugin header in ajax-load-more.php or use wp plugin get ajax-load-more to see the Version fieldAffected if Version is lower than 7.8.2 (the fixed version)
-
Confirm endpoint accessibilitySend a GET request to /wp-admin/admin-ajax.php?action=ajax_load_more or /wp-json/ajax-load-more/v1/posts without authentication cookiesAffected if Request returns post data without requiring authentication (status 200)
-
Check for exposure of non-published contentInspect API response for posts with status: private, draft, pending, scheduled, or trash - these should NOT appear for unauthenticated usersAffected if Response contains posts with non-published status without valid authentication
You are affected if Ajax Load More plugin versions below 7.8.2 are installed and the ajax-load-more endpoint responds without authentication, exposing non-published post content.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the plugin to version 7.8.2 or later which contains the authorization fix. Until then, restrict access to the ajax-load-more endpoint via server-side rules or disable the plugin if not needed.
