CVE-2025-59582 Overview
CVE-2025-59582 is a sensitive data exposure vulnerability in the Ajax Load More plugin for WordPress, developed by Darren Cooney. The flaw affects all versions up to and including 7.6.0.2. An unauthenticated remote attacker can retrieve embedded sensitive system information exposed by the plugin over the network. The issue is classified under CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere.
Critical Impact
Remote unauthenticated attackers can extract sensitive information embedded by the plugin, aiding reconnaissance and follow-on attacks against WordPress sites.
Affected Products
- Darren Cooney Ajax Load More plugin for WordPress
- All versions from n/a through <= 7.6.0.2
- WordPress sites with the ajax-load-more plugin installed and active

Technical Details for CVE-2025-59582
Vulnerability Analysis
The Ajax Load More plugin exposes sensitive system information to unauthenticated callers over standard WordPress request paths. The plugin embeds data that should remain confined to server-side execution, allowing an unauthorized control sphere to retrieve it. Because the flaw is network-reachable and requires no authentication or user interaction, mass scanning against WordPress fleets is straightforward.
The exposed data can include internal identifiers, configuration values, or other embedded artifacts that assist attackers in mapping the environment. While the vulnerability does not directly enable code execution or data modification, disclosed information often reduces the effort required to chain subsequent attacks against the WordPress instance or its hosting infrastructure. The EPSS probability of 0.661% (percentile 47.6) indicates moderate near-term exploitation interest.
Root Cause
The root cause is improper scoping of sensitive information within plugin responses, mapped to [CWE-497]. The plugin returns or renders data that should be restricted to privileged contexts, without enforcing an authentication or capability check on the request path serving that information.
Attack Vector
Exploitation occurs over the network against the WordPress site hosting the vulnerable plugin. An attacker issues crafted HTTP requests to plugin-exposed endpoints and parses the response for embedded sensitive values. No credentials, tokens, or user interaction are required. Refer to the Patchstack Vulnerability Report for technical details.
Detection Methods for CVE-2025-59582
Indicators of Compromise
- Unauthenticated HTTP requests to ajax-load-more plugin endpoints from unfamiliar IP addresses or scanner user agents
- Elevated response sizes from plugin URIs containing configuration or system-context strings
- Repeated enumeration patterns against WordPress sites hosting the ajax-load-more plugin
Detection Strategies
- Inventory WordPress installations to identify sites running Ajax Load More at or below version 7.6.0.2
- Inspect web server access logs for anonymous GET or POST requests targeting admin-ajax.php with Ajax Load More action parameters
- Deploy a web application firewall rule that flags responses containing sensitive tokens returned by the plugin
Monitoring Recommendations
- Alert on spikes in outbound response volume from WordPress endpoints serving ajax-load-more actions
- Track user-agent and source-IP diversity for requests to the plugin to identify automated scanning
- Correlate plugin request patterns with subsequent authentication or exploitation attempts against the same WordPress host
How to Mitigate CVE-2025-59582
Immediate Actions Required
- Upgrade Ajax Load More to a fixed version above 7.6.0.2 as published by the vendor
- If an upgrade is not immediately possible, disable the ajax-load-more plugin until it is patched
- Review recent access logs for signs of enumeration against plugin endpoints and rotate any secrets that may have been exposed
Patch Information
Refer to the Patchstack Vulnerability Report for vendor patch availability. Update via the WordPress plugin management console once a version newer than 7.6.0.2 is available in the plugin repository.
Workarounds
- Restrict access to wp-admin/admin-ajax.php handlers registered by Ajax Load More using a web application firewall until patched
- Apply IP allow-listing at the reverse proxy for administrative and plugin-specific endpoints where feasible
- Remove or deactivate the plugin on public-facing sites that do not require its functionality
