Security Alert Summary
The Ajax Load More WordPress plugin before 7.8.4 fails to sanitise and escape a parameter before outputting it back into the page, resulting in a reflected Cross-Site Scripting (XSS) vulnerability. An attacker can use a crafted link or payload to execute script in the context of a user who visits that link, which may be used against high privilege users such as administrators.
CVE Details
- CVE ID: CVE-2026-6495
- Affected component: Ajax Load More WordPress plugin
- Affected versions: Versions before 7.8.4
- Published: May 18, 2026 at 7:16 AM UTC

- CVSS v3.1: 7.1 (HIGH) CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L
- Authentication / Privileges / User interaction: No authentication required; privileges required: None; user interaction: Required
- Primary impact: Confidentiality: Low; Integrity: Low; Availability: Low
- Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation, Reflected XSS)
Technical Details
The vulnerability exists because a parameter is not sanitised and escaped before being output back into the page. This missing input handling allows an attacker to craft a URL or payload that causes browser-executed script when a user visits the link, producing a reflected XSS condition.
The CVE description does not name specific functions, files, or REST API endpoints, so this advisory does not identify precise code paths. The root cause is inadequate output encoding and input validation for a user-controllable parameter.
Impact is limited to the capabilities of reflected XSS: execution of attacker-supplied script in the context of a victim user. Depending on what the targeted user can access in the admin interface and what other protections are in place, this could allow reading of page content available to that user, performing actions that the user can perform in their browser session, or disclosure of session-related information.
How This Could Impact Your Website
Consider a site owner, an internal editor, and an external contractor who all have elevated access to the WordPress admin. If one of those users opens a crafted link that exploits this reflected XSS, the attacker could execute JavaScript as that user in their browser. Practical consequences include limited disclosure of admin-screen content the user can view, exposure of internal user email addresses visible in the dashboard, and an increased risk of targeted phishing or social engineering against staff or contributors.
The CVSS data shows low impacts to confidentiality, integrity, and availability, but the changed scope indicates the issue can affect areas beyond the originating component when privileged users are targeted. If youre unsure whether your site is affected or how to assess your current user roles and plugins, it may be worth having a professional review.
Recommended Actions
- Update the affected plugin as soon as a patched version is available.
- Review and reduce unnecessary user roles, especially contributor and editor accounts.
- Enforce strong passwords and enable two-factor authentication for editors and administrators.
- Remove unused or unmaintained plugins from your site.
- Monitor site activity and logs for unusual behavior, particularly around administrative actions and login events.
