Attack Vectors

This Medium-severity issue (CVSS 5.3) affects the WordPress plugin Ajax Load More – Infinite Scroll, Load More, & Lazy Load (slug: ajax-load-more) in versions 7.8.1 and below. Because the weakness can be triggered over the network without a user clicking anything, an unauthenticated attacker may be able to query content in ways your team did not intend.

From a business perspective, the practical attack scenario is straightforward: someone who is not logged in can attempt to retrieve information associated with content that is meant to be non-public (such as private or draft items), and then use that information for competitive intelligence, reputational harm, or to time external messaging around your internal announcements.

Security Weakness

CVE-2025-15525 is caused by incorrect authorization in the plugin’s parse_custom_args() function in all versions up to and including 7.8.1. In plain terms, the plugin may not properly enforce who is allowed to access certain post details when processing requests.

As a result, unauthenticated visitors can potentially expose titles and excerpts of content that is normally restricted, including private, draft, pending, scheduled, and trashed posts. While this does not indicate full content exposure or site takeover based on the published information, it is still a meaningful confidentiality risk for organizations that rely on WordPress for content operations and marketing planning.

Technical or Business Impacts

The primary impact is information disclosure: the titles and excerpts of non-public posts may become visible to outsiders. For marketing directors and executives, this can translate into premature disclosure of product launches, campaign themes, partnerships, pricing changes, hiring announcements, or crisis-response drafts—often before Legal, Compliance, or executive leadership has approved release.

Operationally, this can create brand and compliance risk: competitors may gain early insight into strategy, journalists or influencers could surface incomplete messaging, and internal teams may lose control over timing and narrative. Even when only “snippets” are exposed, titles and excerpts frequently contain enough context to infer confidential initiatives.

Remediation: update Ajax Load More – Infinite Scroll, Load More, & Lazy Load to version 7.8.2 or newer, which is the vendor-patched release referenced in the advisory.
