The Ajax Load More - Filters plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'taxonomy_include_children' parameter in all versions up to, and including, 3.4.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Wordfence rates it CVSS 7.2 with a changed scope, reflecting that injected script runs in the context of other site visitors and administrators. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The target site must be running the Ajax Load More - Filters plugin at version 3.4.1 or earlier with filter functionality that processes the 'taxonomy_include_children' parameter. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C, C:L/I:L/A:N, score 7.2) indicates a network-reachable, low-complexity, unauthenticated stored XSS with a scope change - a genuinely meaningful issue for any internet-facing WordPress site running this add-on. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker submits a crafted request that places a malicious value (for example an HTML/script payload) into the 'taxonomy_include_children' parameter, which the plugin stores and later renders unescaped on a filter-driven page. When a site administrator or visitor subsequently loads that page, the script executes in their browser session, enabling session/cookie theft, admin-action forgery, or redirection. … |
| Remediation | No vendor-released patch version is identified in the available data; affected versions are stated as all releases up to and including 3.4.1, so administrators should monitor https://ajaxloadmore.com/add-ons/filters/ and the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/6e8d9f73-8460-4bcb-a9f8-08eb058bcc09?source=cve) for a fixed release (expected to be the next version above 3.4.1) and upgrade immediately once published. … Detailed patch versions, workarounds, and compensating controls in full report. |
